On the night of March 17/18 this umbrella of northern lights unfolded over backyards in Vallentuna, Sweden about 30 kilometers north of Stockholm. A result of the strongest geomagnetic storm of this solar cycle, auroral displays were captured on that night from back and front yards at even lower latitudes, including sightings in the midwestern United States. A boon for aurora hunting skywatchers, the space storm began building when a coronal mass ejection, launched by solar activity some two days earlier, struck planet Earth’s magnetosphere. So what’s the name of the backyard observatory on the right of the wide field view? That’s Carpe Noctem Observatory, of course.

在3月17日至18日的夜晚，瑞典瓦倫圖納（Vallentuna）約30公里北於斯德哥爾摩的後院裡展現出這個北極光的傘形景象。這是此次太陽周期中最強的地磁風暴所引起，當晚的極光顯示甚至在更低緯度的地區被捕捉到，包括美國中西部的目擊。這對喜愛觀賞極光的天文愛好者來說無疑是一個好消息，這場太空風暴始於兩天前由太陽活動發出的日冕物質拋射（coronal mass ejection）撞擊地球的磁氣層。你們知道右邊的後院觀測站叫什麼名字嗎？當然是Carpe Noctem Observatory！
