3月31日凌晨，在地球北纬44度的晴朗天空中，人们捕捉到了这近乎超凡脱俗的北极光。在五秒钟的曝光中，从加拿大新斯科舍省的马提尼克海滩省立公园向北望去。w形仙后座的恒星在地平线上闪闪发光，通过高海拔的红色极光。极光活动是由天空观测者预测的，他们被太阳观测的航天器警告可能出现暴风雨的太空天气。预测的地磁风暴是由日冕物质抛射引发的，从多产的太阳活动区2975发射，影响了我们美丽星球的磁层。

This almost otherworldly display of northern lights was captured in clear skies during the early hours of March 31 from 44 degrees north latitude, planet Earth. In a five second exposure the scene looks north from Martinique Beach Provincial Park in Nova Scotia, Canada. Stars of the W-shaped constellation Cassiopeia shine well above the horizon, through the red tint of the higher altitude auroral glow. Auroral activity was anticipated by skywatchers alerted to the possibility of stormy space weather by Sun-staring spacecraft. The predicted geomagnetic storm was sparked as a coronal mass ejection, launched from prolific solar active region 2975, impacted our fair planet's magnetosphere.
