Tonight's Sky for November 10: Be Alert for Aurora


On November 7, sunspot AR2205 erupted in a X-flare, hurling out a coronal mass ejection (CME) into space. Now, 3 days later, that CME is finally set to impact the Earth's magnetic field. Initially, it was predicted that this CME would miss Earth altogether. Now, space weather forecasters at NOAA are predicting a direct hit, with up to a 75% chance for geomagnetic storms, which can produce brilliant displays of aurora, also known as the Northern Lights. Needless to say, be alert for aurora tonight, especially if you live in high Northern latitudes.
