Practice it Examples Notes & Tips aurora boreal in 30 Seconds

Explanation aurora boreal in your Level:

At the A1 level, you should learn that 'aurora boreal' is the name for the beautiful green lights in the sky in cold countries like Norway or Canada. It is a feminine word, so we say 'a aurora boreal'. You can use simple sentences like 'A aurora boreal é bonita' (The northern lights are beautiful) or 'Eu vejo a aurora boreal' (I see the northern lights). Focus on the colors: 'verde' (green), 'azul' (blue), and 'roxo' (purple). At this stage, you don't need to know the science, just that it is a 'fenômeno' (phenomenon) in the 'céu' (sky) at 'noite' (night). Think of it as a special kind of 'luz' (light). You might see pictures of it in your textbook. Remember that 'boreal' means 'North'. If you see it in a sentence, it usually means something wonderful is happening in a cold place. Practice saying 'A-u-ro-ra Bo-re-al' slowly to get the vowels right. Portuguese vowels are very clear. The 'au' sounds like 'ow' in 'now', and the 'ro' is a quick tap of the tongue. This word will help you talk about travel and nature in a very basic way. Even at A1, knowing this word makes your vocabulary sound more interesting because it is a very specific and famous term. You can also learn the word 'frio' (cold) because you only see the aurora when it is very cold and dark. 'Está frio e eu vejo a aurora boreal' is a perfect A1 sentence. It combines weather, feelings, and a specific object. Don't worry about the plural yet, just focus on the singular 'a aurora boreal'.

At the A2 level, you can start using 'aurora boreal' to talk about travel plans and past experiences. You might say, 'Eu quero viajar para a Islândia para ver a aurora boreal' (I want to travel to Iceland to see the northern lights). You should also learn the plural form: 'as auroras boreais'. Notice how 'boreal' becomes 'boreais'. This is a common rule for adjectives ending in 'l'. You can describe the lights with more adjectives like 'espetacular' (spectacular) or 'misteriosa' (mysterious). At this level, you can understand simple descriptions: 'A aurora boreal acontece no norte do mundo' (The aurora boreal happens in the north of the world). You can also use verbs like 'olhar' (to look) and 'tirar fotos' (to take photos). 'Eu tirei muitas fotos da aurora boreal' is a great sentence to practice the past tense. You might also encounter this word in weather reports or travel advertisements. It's important to recognize that 'aurora' is a feminine noun, so any adjective you use must agree with it. For example, 'uma aurora boreal incrível'. If you are talking to a friend about your dream trip, you could say 'Meu sonho é presenciar uma aurora boreal'. The verb 'presenciar' is a bit more advanced than 'ver' but very common for this context. You should also be able to answer simple questions like 'Onde podemos ver a aurora boreal?' (Where can we see the northern lights?) with answers like 'Na Noruega' or 'No Alasca'. This builds your geographical and environmental vocabulary simultaneously.

At the B1 level, you can describe the 'aurora boreal' in more detail and explain why it happens in simple terms. You can use words like 'partículas' (particles), 'atmosfera' (atmosphere), and 'campo magnético' (magnetic field). You can explain the experience of seeing it: 'Foi uma experiência inesquecível ver a aurora boreal dançando sobre as montanhas' (It was an unforgettable experience to see the northern lights dancing over the mountains). You should be comfortable using the term in complex sentences with conjunctions like 'porque' (because) or 'embora' (although). For example: 'Embora estivesse muito frio, nós ficamos fora para ver a aurora boreal'. You can also discuss the best conditions for seeing them, such as 'céu limpo' (clear sky) and 'baixa poluição luminosa' (low light pollution). This level requires you to understand the difference between 'aurora boreal' and 'aurora austral'. You can talk about the 'ciclo solar' (solar cycle) and how it affects the frequency of the lights. In a conversation, you might discuss travel tips: 'É preciso ter paciência para caçar a aurora boreal, pois ela nem sempre aparece'. The expression 'caçar a aurora' (to hunt the aurora) is very common among travelers. You can also start using more evocative verbs like 'surgir' (to emerge/appear) or 'desaparecer' (to disappear). 'De repente, a aurora boreal surgiu no horizonte'. Your ability to connect the phenomenon to emotions and specific travel conditions shows you are moving into the intermediate range. You can also read short articles in Portuguese about the best places to see the lights and summarize them using the term correctly.

At the B2 level, you should be able to discuss the 'aurora boreal' from a scientific and technical perspective. You can explain the interaction between the 'vento solar' (solar wind) and the 'magnetosfera' (magnetosphere). You should use precise vocabulary like 'ejeção de massa coronal' (coronal mass ejection), 'oxigênio' (oxygen), and 'nitrogênio' (nitrogen) to describe how different colors are formed. For instance, 'O oxigênio em altitudes elevadas produz a cor vermelha da aurora boreal'. You can participate in a debate or a presentation about natural phenomena, using the term fluently. You should also be aware of the historical context, such as how the term was coined by Galileo Galilei or Pierre Gassendi. At B2, you can understand nuanced texts that describe the aurora's impact on technology, such as 'interferência em satélites' (interference in satellites) or 'redes elétricas' (power grids). You can use the term metaphorically in writing: 'A sua beleza era como uma aurora boreal, brilhante mas passageira'. You should also be able to handle the plural 'auroras boreais' and its agreement in complex structures: 'As auroras boreais observadas no último século foram documentadas por cientistas'. You might also explore the mythology of northern peoples (like the Sami or Inuit) and how they interpreted the 'aurora boreal', translating these concepts into Portuguese. This shows a deep integration of cultural, scientific, and linguistic knowledge. You can also contrast the 'aurora boreal' with other atmospheric events like 'nuvens noctilucentes' (noctilucent clouds) or 'luz zodiacal' (zodiacal light), demonstrating a high level of specialized vocabulary.

At the C1 level, you can use 'aurora boreal' in highly sophisticated and academic contexts. You can write essays or give detailed lectures on the geophysics of the polar regions, incorporating the term seamlessly. You should be able to appreciate and analyze literary passages where the aurora is used as a central motif. For example, analyzing how a Portuguese poet might use the 'aurora boreal' to represent the 'sublime'—a beauty that is both terrifying and magnificent. You can discuss the philosophical implications of such a phenomenon, such as our place in the universe. Your vocabulary should include terms like 'ionosfera' (ionosphere), 'fluorescência' (fluorescence), and 'quiescência' (quiescence). You can navigate complex news reports that discuss the 'mínimo solar' and 'máximo solar' and their effects on the visibility of the 'aurora boreal'. In conversation, you can use the term with stylistic flair, perhaps using archaic or rare synonyms like 'lume vivo' if the context allows for poetic license. You should also be able to explain the socio-economic impact of 'turismo de aurora' in countries like Norway or Iceland, using terms like 'sustentabilidade' (sustainability) and 'infraestrutura' (infrastructure). At this level, your understanding of the term includes its phonetic nuances in different Portuguese dialects and its symbolic weight in various Lusophone cultures. You can provide a deep critique of a documentary or a scientific paper on the subject, noting the precision of the language used to describe the 'manifestações das auroras boreais'.

At the C2 level, you have a masterly command of the term 'aurora boreal' and all its scientific, cultural, and linguistic associations. You can speak about the phenomenon with the same level of detail as a native expert, perhaps a physicist or a seasoned travel writer. You can engage in deep discussions about the 'magnetohidrodinâmica' (magnetohydrodynamics) that governs the 'aurora boreal'. You understand the most subtle metaphorical uses in contemporary Portuguese literature and can produce your own creative writing that utilizes the term in innovative ways. You can effortlessly switch between the scientific 'aurora boreal' and the more colloquial 'luzes do norte' depending on your audience, always maintaining perfect grammatical and stylistic control. You are familiar with rare historical accounts written in Portuguese about the lights, perhaps from early explorers or scientists. You can analyze how the 'aurora boreal' is represented in different media—from digital photography to classical painting—and discuss these representations using advanced aesthetic terminology. Your ability to explain the phenomenon includes an understanding of its 'assinatura espectral' (spectral signature) and its role in the broader context of 'clima espacial' (space weather). At this level, the term is not just a vocabulary word but a gateway to a vast web of knowledge that you can navigate with ease, precision, and elegance. You can even discuss the 'sonoplastia' (sound design) in films that attempt to recreate the supposed 'sounds' of the aurora boreal, using highly specific vocabulary.

Practice it Examples Notes & Tips

aurora boreal in 30 Seconds

A natural light display in the Northern Hemisphere's night sky.
Caused by solar particles interacting with Earth's magnetic field and atmosphere.
Most commonly seen in shades of green, purple, and red.
A major tourist attraction in countries like Norway, Iceland, and Canada.

The term aurora boreal refers to one of nature's most spectacular displays: the Northern Lights. In Portuguese, this noun phrase is used to describe the luminous atmospheric phenomenon that occurs in the high-latitude regions of the Northern Hemisphere. It is characterized by vibrant curtains, rays, or spirals of light that dance across the night sky, typically in shades of green, pink, and purple. The word 'aurora' refers to the Roman goddess of the dawn, while 'boreal' comes from the Greek word 'Boreas,' representing the north wind. Therefore, the literal translation suggests a 'northern dawn,' though the phenomenon is quite different from a standard sunrise.

Scientific Context: People use this term most frequently in scientific discussions regarding geophysics and astronomy. It describes the interaction between solar wind particles and the Earth's magnetic field. When these charged particles collide with gases in the upper atmosphere, they release energy in the form of light.

Muitos turistas viajam para a Noruega apenas para ver a aurora boreal dançando no céu de inverno.

Beyond science, the term is heavy with poetic and romantic connotations. In Portuguese literature and travel writing, it evokes a sense of wonder, isolation, and the sublime beauty of the Arctic. It is often a 'bucket list' item for Portuguese speakers who dream of traveling to cold climates like Iceland, Finland, or Canada. You will hear it in documentaries, see it in travel brochures, and find it in news reports when a particularly strong solar storm makes the lights visible further south than usual.

Cultural Nuance: In Portuguese-speaking countries like Brazil or Portugal, which are far from the poles, the aurora boreal is seen as an exotic and almost mythical event. It represents the ultimate adventure into the unknown northern territories.

A aurora boreal é um dos fenômenos mais fotografados do mundo devido à sua beleza única.

The term is also used metaphorically occasionally to describe something transient, ethereal, and brilliantly beautiful. However, its primary use remains literal. In the context of global warming and environmental science, the visibility and frequency of the aurora boreal are sometimes discussed alongside changes in the Earth's atmosphere and magnetic protection. It is a term that bridges the gap between hard physics and pure aesthetic appreciation.

Dizem que a aurora boreal faz um som sutil, como um estalido, embora poucos consigam ouvi-lo.

Seasonal Usage: You will notice the term appearing more frequently in Portuguese media during the winter months of the Northern Hemisphere (December to March), as this is the peak viewing season for the phenomenon.

A melhor época para observar a aurora boreal é entre os meses de setembro e abril.

Cientistas estudam a aurora boreal para entender melhor o clima espacial e seu impacto na Terra.

Using aurora boreal in a sentence requires an understanding of its role as a feminine noun phrase. In Portuguese, adjectives and articles must agree with the noun 'aurora'. Because 'boreal' is an adjective that ends in 'l', its plural form changes to 'boreais'. Therefore, if you are talking about multiple occurrences, you would say 'as auroras boreais'. This is a common point of confusion for learners who might try to say 'auroras boreals', which is incorrect.

Verbs of Observation: When talking about the aurora, we often use verbs like 'ver' (to see), 'observar' (to observe), 'presenciar' (to witness), and 'contemplar' (to contemplate/gaze upon). 'Presenciar' is particularly common because it emphasizes the rarity and significance of the event.

Eu tive a sorte de presenciar uma aurora boreal intensa durante minha viagem à Islândia.

In more technical or descriptive writing, you might use the verb 'ocorrer' (to occur) or 'manifestar-se' (to manifest). These verbs shift the focus from the observer to the phenomenon itself. For example, a textbook might explain where the lights occur geographically. Note that 'boreal' specifically denotes the North; if you were in Antarctica, you would use 'aurora austral'. Mixing these up is a common geographical error in Portuguese.

Prepositional Phrases: We often link the aurora to a location using 'em' (in) or 'sobre' (over). For example, 'a aurora boreal sobre os Alpes' (the aurora boreal over the Alps). Using 'sobre' adds a poetic layer, suggesting the lights are hovering or watching over the landscape.

A aurora boreal manifestou-se com cores verdes e púrpuras sobre a floresta congelada.

Another important aspect is the use of frequency adverbs. Since seeing the aurora is often a matter of luck, words like 'raramente' (rarely), 'frequentemente' (frequently), and 'ocasionalmente' (occasionally) are key. In northern Portugal, for instance, one might say that the aurora boreal is 'extremamente rara'. In contrast, in Norway, it is 'muito comum' during the winter. This contrast helps set the context for the listener.

É raro ver uma aurora boreal em latitudes tão baixas como as de Portugal.

Descriptive Adjectives: To enrich your sentences, combine the term with adjectives like 'deslumbrante' (stunning), 'espetacular' (spectacular), 'misteriosa' (mysterious), or 'vívida' (vivid). These help convey the emotional impact of the sight.

O fotógrafo capturou uma imagem deslumbrante da aurora boreal refletida no lago.

As auroras boreais são causadas por ventos solares que atingem a nossa atmosfera.

In the Portuguese-speaking world, you are most likely to encounter the term aurora boreal in educational and media contexts. Because Brazil and Portugal are not located in the Arctic Circle, the word carries a sense of international travel and scientific discovery. Television programs like 'Globo Repórter' in Brazil or 'Biosfera' in Portugal often feature episodes about the wonders of the North, where the aurora boreal is a central theme. These documentaries use high-definition footage to showcase the lights, often accompanied by a narrator describing the 'dança das luzes' (dance of the lights).

News and Science Journals: Whenever there is a significant solar storm, Portuguese news outlets (like SIC, RTP, or G1) will report on the possibility of seeing the lights. They might use headlines like 'Forte tempestade solar pode gerar aurora boreal visível em regiões incomuns'. This is where you will hear the term used with technical precision, often alongside words like 'campo magnético' (magnetic field) and 'partículas solares'.

O telejornal anunciou que uma aurora boreal foi vista até mesmo no norte da Escócia ontem à noite.

Social media and travel blogs are other major sources. Influencers from Portugal and Brazil who travel to 'destinos gelados' (frozen destinations) will frequently use the hashtag #auroraboreal. They share tips on 'caçar a aurora boreal' (hunting the northern lights), which has become a popular phrase among travel enthusiasts. In this context, the language is less formal and more experiential, focusing on the cold, the waiting, and the eventual payoff of seeing the lights. You might hear someone say, 'Estamos aqui no frio, esperando a aurora boreal aparecer'.

Educational Settings: In schools across the Lusophone world, the aurora boreal is a standard topic in geography and physics classes. Students learn about the Earth's poles and the magnetosphere. Here, the term is used to explain complex natural laws. Teachers might use diagrams to show how the 'aurora boreal' differs from the 'aurora austral'.

Na aula de geografia, aprendemos que a aurora boreal ocorre apenas no Hemisfério Norte.

Finally, you will find the term in literature and music. Portuguese fado or Brazilian MPB (Música Popular Brasileira) might use the 'aurora boreal' as a metaphor for something fleeting or a distant dream. It represents a beauty that is unreachable for many, making it a powerful symbol in artistic expression. Whether in a scientific journal or a romantic poem, the term carries a weight of awe and respect for the natural world.

A letra da música comparava o brilho dos olhos dela com a luz de uma aurora boreal.

Photography Communities: Photography workshops in Portugal often organize trips to Lapland. In these circles, 'aurora boreal' is discussed in terms of 'exposição' (exposure), 'tripé' (tripod), and 'ISO', focusing on the technical challenge of capturing the light.

Para fotografar a aurora boreal, é necessário usar uma longa exposição e manter a câmera estável.

One of the most frequent mistakes English speakers make when using the term aurora boreal in Portuguese is regarding gender agreement. In English, nouns don't have gender, but in Portuguese, 'aurora' is a feminine noun. Many learners mistakenly use the masculine article 'o' because the phenomenon seems grand or 'neutral' in their mind. Always remember: it is 'a aurora boreal'. Saying 'o aurora boreal' sounds very unnatural to a native speaker and is a clear indicator of a beginner level.

Pluralization Errors: Another common pitfall is the plural form. In Portuguese, adjectives ending in '-al' change to '-ais' in the plural. Therefore, 'aurora boreal' becomes 'auroras boreais'. Learners often try to add a simple 's' to 'boreal' (making it 'boreals'), which does not exist in Portuguese grammar. This rule applies to many words like 'animal/animais' or 'final/finais'.

Errado: Eu vi muitos auroras boreals.
Correto: Eu vi muitas auroras boreais.

Geographical confusion is also a significant issue. 'Boreal' specifically refers to the North. If you are discussing the lights seen in the Southern Hemisphere (like in New Zealand or Antarctica), you must use 'aurora austral'. Using 'aurora boreal' to describe the lights in the South is technically incorrect. While people might understand you, it shows a lack of precision. It's like calling the North Pole the South Pole.

Pronunciation of 'Boreal': The pronunciation of the 'L' at the end of 'boreal' can be tricky. In Brazilian Portuguese, the final 'L' often sounds like a 'U' (/bo.re.ˈaw/), whereas in European Portuguese, it is a 'dark L' (/bu.ɾi.ˈaɫ/). English speakers often over-pronounce the 'L' like in the English word 'real', which can sound off. Aim for the softer, vocalized version if you are aiming for a Brazilian accent.

Dica: Pratique a transição de 'aurora' para 'boreal' sem fazer uma pausa longa, mantendo o fluxo da frase.

Finally, avoid overusing the word when 'luzes' would suffice in casual conversation. While 'aurora boreal' is the correct term, repeatedly saying it in a story can sound a bit repetitive or overly formal. You can vary your vocabulary by using 'luzes do norte' or simply referring to 'o fenômeno' once the context has been established. This makes your Portuguese sound more natural and less like a textbook.

Não diga: A aurora boreal foi linda. Eu amei a aurora boreal. A aurora boreal é verde.
Diga: A aurora boreal foi linda. Eu amei as luzes. O fenômeno é verde.

Spelling Note: In Portuguese, 'boreal' is not capitalized unless it starts a sentence or is part of a specific proper title. Some learners capitalize it because 'Northern Lights' is often capitalized in English titles.

Correto: Eu quero ver a aurora boreal.
Incorreto: Eu quero ver a Aurora Boreal.

While aurora boreal is the most precise scientific term, Portuguese offers several alternatives and related terms depending on the context. The most direct synonym used in casual speech is luzes do norte. This is a literal translation of 'Northern Lights' and is perfectly acceptable in almost all situations. It feels slightly more informal and is very common in travel blogs and everyday conversation.

Aurora Boreal vs. Aurora Austral

Aurora Boreal: Occurs in the Northern Hemisphere (Arctic).

Aurora Austral: Occurs in the Southern Hemisphere (Antarctic). They are physically the same phenomenon but differentiated by geography.

Enquanto a aurora boreal brilha na Noruega, a aurora austral ilumina os céus da Antártida.

Another related term is aurora polar. This is the umbrella term that includes both the boreal and austral versions. You will see this in scientific papers when the specific pole doesn't matter. If you want to sound more poetic, you might use luzes polares. This evokes the cold, distant nature of the poles and is often used in literature.

Contextual Alternatives: If you are describing the visual effect without using the formal name, you might say 'brilho atmosférico' (atmospheric glow) or 'fenômeno luminescente' (luminescent phenomenon). These are much more technical and used primarily in physics or meteorology.

O fenômeno luminescente foi causado por uma ejeção de massa coronal do sol.

In some older Portuguese texts, you might find the term fogo de santelmo mentioned in similar contexts, although this is a completely different electrical phenomenon (St. Elmo's Fire). It's important to distinguish them: the aurora is high in the atmosphere, while St. Elmo's Fire occurs on the tips of masts or lightning rods during storms. Knowing the difference shows a high level of vocabulary mastery.

Comparison of Terms

Aurora Boreal: Formal, scientific, specific to North.
Luzes do Norte: Common, descriptive, friendly.
Aurora Polar: General scientific category.
Fenômeno Celeste: Broad, poetic, emphasizes the sky.

Muitos preferem o termo luzes do norte por ser mais fácil de lembrar em conversas informais.

How to Use It

Common in travel and science contexts, rare in daily urban life in Lusophone countries.

Common Mistakes

O aurora boreal → A aurora boreal
'Aurora' is a feminine noun in Portuguese, so it requires the feminine article 'a'.
Auroras boreals → Auroras boreais
Adjectives ending in '-al' form their plural by changing to '-ais'.
Using 'boreal' for the South Pole → Aurora austral
'Boreal' specifically means 'North'. For the South, use 'austral'.
Capitalizing 'aurora boreal' mid-sentence → aurora boreal
In Portuguese, common nouns and adjectives are not capitalized unless they start a sentence.
Pronouncing 'boreal' like English 'real' → bo-re-AL (with a flap R and soft L)
The pronunciation follows Portuguese rules, not English ones.

Tips

Look North

Always look toward the northern horizon. The aurora usually starts as a faint green glow in the north before spreading across the sky.

Use a Tripod

Long exposure is key. Even a small movement will blur the lights, so a sturdy tripod is essential for those crisp, dancing light shots.

Dress in Layers

You will be standing still for a long time in sub-zero temperatures. Wear wool base layers and a high-quality parka to stay warm.

Check the Kp-Index

Use apps like 'My Aurora Forecast' to check the Kp-index, which measures geomagnetic activity. A higher number means a better chance of seeing the lights.

Be Patient

The aurora is a natural event and doesn't follow a schedule. Be prepared to wait several hours in the cold for the magic to happen.

Escape City Lights

Light pollution from cities will drown out the aurora. Drive at least 30 minutes away from urban centers for the best experience.

Stay Hydrated and Fed

The cold drains your energy. Bring a thermos with hot coffee or tea and some high-energy snacks to keep your spirits up.

Drive Safely

Winter roads in aurora regions can be icy and dangerous. Make sure your rental car has studded tires and you have an emergency kit.

Let Eyes Adjust

It takes about 20 minutes for your eyes to fully adjust to the dark. Avoid looking at your bright phone screen while waiting.

Respect Other Photographers

If you are in a popular spot, don't use flash or bright headlamps, as it ruins the long-exposure shots and night vision of others.

Memorize It

Mnemonic

Think of 'Aurora' as the Princess (Dawn) and 'Boreal' as the North (Boreas). The Princess of the North Dawn.

Visual Association

Imagine a green curtain dancing over a snowy forest in Norway.

Challenge

Try to describe the colors of the aurora boreal to a friend using only Portuguese adjectives.

Word Origin

The term 'aurora' comes from the Latin 'aurora', which was the name of the Roman goddess of the dawn. The word 'boreal' comes from the Latin 'borealis', which is derived from 'Boreas', the Greek god of the North Wind.

Original meaning: Northern Dawn.

Latin/Greek roots via Romance (Portuguese).

Cultural Context

Be respectful of indigenous interpretations of the lights when discussing them in a cultural context.

English speakers often call them 'Northern Lights', but in formal Portuguese, 'aurora boreal' is the standard.

The movie 'Brother Bear' (Irmão Urso) features the lights prominently. Documentaries by David Attenborough (dubbed in Portuguese). Philip Pullman's 'Northern Lights' (A Bússola de Ouro in Portuguese).

Frequently Asked Questions

10 questions

É extremamente raro ver a aurora boreal em Portugal devido à sua latitude sul. No entanto, durante tempestades solares muito intensas, um brilho avermelhado pode ocasionalmente ser detectado no horizonte norte, embora não seja a exibição vibrante vista na Escandinávia.

A cor mais comum e brilhante é o verde, causada pelo oxigênio. No entanto, muitas pessoas consideram o roxo e o vermelho as cores mais bonitas e raras. A 'melhor' cor é subjetiva e depende da preferência do observador.

Existem relatos de pessoas que ouvem sons como estalidos ou sussurros durante auroras intensas. Cientistas confirmaram recentemente que esses sons podem ocorrer devido a descargas elétricas na atmosfera, mas são difíceis de capturar.

No extremo norte, como na Noruega ou Islândia, não é possível ver a aurora boreal no verão porque o céu nunca fica escuro o suficiente devido ao sol da meia-noite. É necessário ter escuridão total para observá-la.

Uma exibição pode durar de alguns minutos a várias horas. Ela pode aparecer e desaparecer várias vezes durante uma única noite, dependendo da atividade solar e das condições atmosféricas.

Não, a aurora boreal não é perigosa para os seres humanos na Terra, pois a nossa atmosfera e o campo magnético nos protegem das partículas solares. No entanto, ela pode afetar sistemas de GPS e redes elétricas.

A única diferença real é a localização geográfica. A aurora boreal ocorre no Hemisfério Norte (Ártico) e a aurora austral ocorre no Hemisfério Sul (Antártida). Elas são fenômenos espelhados causados pelo mesmo processo.

Para ver a aurora boreal, você só precisa de seus olhos e um céu escuro. No entanto, para fotografá-la, você precisará de uma câmera com controles manuais e um tripé estável.

A atividade que causa a aurora acontece quase constantemente, mas a visibilidade depende da força do vento solar e da clareza do céu. Em lugares como Tromsø, ela é visível na maioria das noites claras de inverno.

A cor verde é produzida quando partículas solares colidem com moléculas de oxigênio em altitudes de cerca de 100 a 300 quilômetros. É a reação química mais eficiente e frequente na nossa atmosfera.
