其他極光觀測者都回家了。在冰島一個寧靜的九月夜晚，到凌晨 3 : 30 時，當晚的極光大部分已經消散。突然，出人意料的是，一陣新的粒子流從太空飛來，再次照亮了地球的大氣層。這一次，令人驚奇的是，夜空中出現了一個令人驚歎的形狀，讓人聯想到一隻巨大的鳳凰。攝影裝置準備就緒，快速拍攝了兩張天空影像，緊接著又拍攝了三分之一的陸地影像。 背景中的山峰是 Helgafell，而前景中的小河名為 Kaldá，都位於冰島首都雷克雅未克以北約 30 公里處。經驗豐富的觀星者會注意到，山峰正上方左側是獵戶座，而昴宿星團也在畫面中心上方可見。 2016 年的極光只持續了一分鐘，很快就永遠地消失了，如果不是這幅以數字合成的馬賽克影像捕捉到了這一奇觀，人們可能會把它當作一個虛構的寓言。 您的天空驚喜：在您生日那天，APOD 報道了哪張照片？ ( 1995 年後)
原文：All of the other aurora watchers had gone home. By 3:30 am in Iceland, on a quiet September night, much of that night's auroras had died down. Suddenly, unexpectedly, a new burst of particles streamed down from space, lighting up the Earth's atmosphere once again. This time, surprisingly, pareidoliacally, the night lit up with an amazing shape reminiscent of a giant phoenix. With camera equipment at the ready, two quick sky images were taken, followed immediately by a third of the land. The mountain in the background is Helgafell, while the small foreground river is called Kaldá, both located about 30 kilometers north of Iceland's capital Reykjavík. Seasoned skywatchers will note that just above the mountain, toward the left, is the constellation of Orion, while the Pleiades star cluster is also visible just above the frame center. The 2016 aurora, which lasted only a minute and was soon gone forever -- would possibly be dismissed as a fanciful fable -- were it not captured in the featured, digitally-composed, image mosaic.
