This page describes a video Under the Stars with Steve, by Sheila Wiwchar, Canada
Video caption:
Third place in the 2021 IAU OAE Astrophotography Contest, category Aurorae (time-lapses).
This is a strange atmospheric phenomenon known as Steve. This is similar to an aurora as it is caused by charged particles interacting with the Earth's magnetic field. However unlike aurorae, the particles which cause Steve are generated high in the Earth's atmosphere rather than coming from the Sun. Note the banded "picket fence" appearance. This is caused by waves of these particles in the upper atmosphere. The name Steve was chosen by the first group to describe this phenomenon as a familiar name for something unknown.

Video caption: ২০২১ আইএইউ ওএই অ্যাস্ট্রোফটোগ্রাফি প্রতিযোগিতায় তৃতীয় স্থান, ক্যাটাগরি অরোরা (টাইম-ল্যাপস)।
এটি একটি অদ্ভুত বায়ুমণ্ডলীয় ঘটনা যা স্টিভ নামে পরিচিত। এটি একটি অরোরার অনুরূপ কারণ এটি পৃথিবীর চৌম্বক ক্ষেত্রের সাথে মিথস্ক্রিয়া চার্জযুক্ত কণা দ্বারা সৃষ্ট হয়। তবে অরোরার বিপরীতে, স্টিভের সৃষ্টিকারী কণাগুলি সূর্য থেকে আসার পরিবর্তে পৃথিবীর বায়ুমণ্ডলে উচ্চতর উৎপন্ন হয়। ব্যান্ডেড "পিকেট বেড়া" চেহারা নোট করুন। উপরের বায়ুমণ্ডলে এই কণার তরঙ্গের কারণে এটি ঘটে। স্টিভ নামটি অজানা কিছুর জন্য একটি পরিচিত নাম হিসাবে এই ঘটনাটি বর্ণনা করার জন্য প্রথম গ্রুপ দ্বারা বেছে নেওয়া হয়েছিল।

Video caption: Troisième place au concours d'astrophotographie 2021 de l'UAI OAE, catégorie Aurores (images empilées).
Il s'agit d'un étrange phénomène atmosphérique connu sous le nom de Steve. Ce phénomène est similaire à une aurore puisqu'il est causé par des particules chargées qui interagissent avec le champ magnétique de la Terre. Toutefois, contrairement aux aurores, les particules à l'origine de Steve sont générées à haute altitude dans l'atmosphère terrestre et ne proviennent pas du Soleil. Notez l'aspect en bandes de l'image. Ce phénomène est causé par les ondes de ces particules dans la haute atmosphère. Le nom Steve correspond en fait l’acronyme anglais de Strong Thermal Emission Velocity Enhancement (forte augmentation de la vitesse d'émission thermique).

Si tratta di uno strano fenomeno atmosferico noto come Steve. È simile a un'aurora perché è causato da particelle cariche che interagiscono con il campo magnetico terrestre. Tuttavia, a differenza delle aurore, le particelle che causano Steve sono generate in alto nell'atmosfera terrestre anziché provenire dal Sole. Si noti come il fenomeno abbia l'aspetto di uno steccato. Questo è causato dalle onde di queste particelle nell'alta atmosfera. Il nome Steve è stato scelto dal primo gruppo che descrisse questo fenomeno come un nome familiare per qualcosa di sconosciuto.

这是一种奇特的大气现象，被称为 "史蒂夫"。它与极光类似，都是由带电粒子与地球磁场相互作用引起的。不过，与极光不同的是，引起史蒂夫现象的粒子是在地球大气层的高处产生的，而不是来自太阳。注意那种带状的 "栅栏 "外观，这是由这些粒子在上层大气中形成的波动引起的。“史蒂夫” 这个名字是第一批描述这种现象的人为未知事物选择的一个耳熟能详的名字。
