Aurora Over Arctic Henge

Explanation: Reports of powerful solar flares started a seven-hour quest north to capture modern monuments against an aurora-filled sky. The peaks of iconic Arctic Henge in Raufarhöfn in northern Iceland were already aligned with the stars: some are lined up toward the exact north from one side and toward exact south from the other. The featured image, taken after sunset late last month, looks directly south, but since the composite image covers so much of the sky, the north star Polaris is actually visible at the very top of the frame. Also visible are familiar constellations including the Great Bear (Ursa Major) on the left, and the Hunter (Orion) on the lower right. The quest was successful. The sky lit up dramatically with bright and memorable auroras that shimmered with amazing colors including red, pink, yellow, and green — sometimes several at once.

北极巨石阵上空的极光

说明: 发生强烈日闪（太阳耀斑）的报导，让摄影者开启了北行7小时的任务，以拍摄现代纪念碑上空满是极光的天空。位于冰岛北部Raufarhöfn村的标志性北极巨石阵（Arctic Henge）之尖顶，与恒星的方位对齐：它的一侧指向正北，另一侧指向正南。在这幅摄于上个月下旬日落后的南眺主题图像里，由于组合图像涵盖了极为广阔的天空，因此北极星实际上位于图像的顶缘。除此之外，清楚可见的熟悉星座，有左侧的大熊座和右下方的猎户座。这项任务非常成功。该地的夜空，因明亮令人难忘的极光而戏剧性的亮起，摇曳的极光更带着令人赞叹的色彩，在红、粉红、黄色及绿之间变幻，有时甚至数种色泽的极光并现。
