Caption: Third place in the 2021 IAU OAE Astrophotography Contest, category Aurorae (still images)

The blurred motions of the aurora caught during the exposure time of this photograph beautifully illustrate its dynamic nature. While certain forms of aurorae, like homogeneous arcs and bands or diffuse glows, can remain static for hours, others, like rayed arcs or bands (also called "curtains"), can change within seconds in shape and brightness.

Caption: الصورة الفائزة بالمركز الثالث في مسابقة التصوير الفلكي التي اقامها مكتب تعليم الفلك التابع لاتحاد الفلك الدولي سنة 2021، فئة الشفق القطبي (الصور الثابتة)

الحركات غير الواضحة للشفق القطبي التي تم التقاطها أثناء وقت التعريض لهذه الصورة توضح طبيعتها الديناميكية بشكل جميل. في حين أن بعض أشكال الشفق القطبي مثل الأقواس والأشرطة المتجانسة أو التوهجات المنتشرة يمكن أن تظل ثابتة لساعات فإن اشكالا اخرى مثل الأقواس أو الأشرطة الشعاعية (وتسمى أيضا "الستائر") ، يمكن أن تتغير في غضون ثوان من حيث الشكل والسطوع.

Caption: Terzo posto al concorso di astrofotografia IAU OAE 2021, categoria Aurorae (immagini fisse)

I movimenti sfocati dell'aurora catturati durante il tempo di esposizione di questa fotografia illustrano magnificamente la sua natura dinamica. Mentre alcune forme di aurore, come gli archi e le bande omogenee o i bagliori diffusi, possono rimanere statiche per ore, altre, come gli archi o le bande raggiate (chiamate anche "tende"), possono cambiare in pochi secondi forma e luminosità.
