A heads-up for all you aurora watchers out there. The NOAA space weather forecast calls for a 30 percent chance for minor geomagnetic storms tonight Jan. 18 through the 20th. That means there’s a small possibility for auroras in the northern U.S. and a much better one for Arctic regions.
The cause behind the next expected wave is another CME or coronal mass ejection. Similar enhancements in the sun’s wind of subatomic particles have been responsible for recent, widely-visible auroras across Finland, Norway, Iceland and Canada. We came close to seeing minor auroras in the northern U.S. last night, but the burst of activity that visited the Scandinavian countries earlier in the day had died down by the time darkness cloaked the U.S.
