A powerful solar explosion on Thursday, Oct 25th, sent a coronal mass ejection (CME) billowing toward Earth. The expanding cloud could trigger auroras when it reaches our planet on Oct 27th or 28th. If so, the coming weekend would be the second in a row that high-latitude sky watchers have enjoyed Northern Lights.
