Tomorrow and Thursday, however, you can blame a different entity in the sky … the Sun.
According to website Spaceweather.com:
Later today, Dec.20th, Earth is expected to enter a stream of solar wind flowing at high speed from a large hole in the sun’s atmosphere. This could set in motion days of magnetic unrest around the poles. NOAA forecasters estimate a 60% chance of minor G1-class geomagnetic storms on Dec. 21st, increasing to 65% on Dec. 22nd.
If you live near the Arctic Circle, watch for a spectacular show of northern lights.
Hmmm… might be a good time to visit Iceland?
