Second place in the 2021 IAU OAE Astrophotography Contest, category Aurorae (still images)
Aurorae often display waving curtain-like patterns where arcs or bands form moving curls, folds, or even spirals. These irregular shapes mirror the small-scale structure of Earth's magnetic field interacting with charged particle flows. Although the full Moon illuminates both the landscape and the night sky, the auroa is easily visible, which demonstrates that it can be a very bright and colourful phenomenon.

Image caption: ২০২১ আইএইউ ওএই অ্যাস্ট্রোফটোগ্রাফি প্রতিযোগিতায় দ্বিতীয় স্থান, অরোরা (স্থির ছবি)
অরোরা প্রায়শই ঢেউ খেলানো পর্দার মতো প্যাটার্ন প্রদর্শন করে যেখানে আর্কস বা ব্যান্ডগুলি চলমান কার্ল, ভাঁজ বা এমনকি সর্পিল গঠন করে। এই অনিয়মিত আকারগুলি আধানযুক্ত কণা প্রবাহের সাথে মিথস্ক্রিয়া করে পৃথিবীর চৌম্বক ক্ষেত্রের ছোট আকারের কাঠামোকে প্রতিফলিত করে। যদিও পূর্ণিমা ল্যান্ডস্কেপ এবং রাতের আকাশ উভয়ই আলোকিত করে, অরো সহজেই দৃশ্যমান হয়, যা প্রমাণ করে যে এটি একটি খুব উজ্জ্বল এবং রঙিন ঘটনা হতে পারে।

Image caption: Secondo posto al concorso di astrofotografia IAU OAE 2021, categoria Aurore (immagini fisse).
Le aurore mostrano spesso modelli simili a tende ondeggianti in cui archi o bande formano riccioli, pieghe o persino spirali in movimento. Queste forme irregolari rispecchiano la struttura su piccola scala del campo magnetico terrestre che interagisce con flussi di particelle cariche. Anche se la Luna piena illumina il paesaggio e il cielo notturno, l'aurora è facilmente visibile, il che dimostra che può essere un fenomeno molto luminoso e colorato.

Image caption: 2021年国际天文学联合会（IAU）OAE天文摄影比赛极光类别（静态图像）二等奖。
极光经常呈现出波浪状的幕布图案，其中的弧形或带状光束会形成移动的卷曲、褶皱，甚至螺旋状结构。这些不规则的形状反映了地球磁场的小尺度结构与带电粒子流之间的相互作用。尽管满月照亮了地景和夜空，极光依然清晰可见，这表明极光可以是一种非常明亮且色彩丰富的现象。
