This page describes an image Iceland aurora, by Emanuele Balboni, Italy
Image 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.

Image 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.

在这张照片曝光时间内捕捉到了极光模糊的运动，生动展现了其动态特性。虽然某些形式的极光（如均匀的弧状和条带或弥散光辉）可以静止持续数小时，但其他形式的极光（如射线状弧或条带，也称为“幕”）的形状和亮度可能在数秒内发生变化。
