If you’re reading this in Scandinavia right now, stop and go outside to look at the northern lights. A modest storm is in progress over Norway, Sweden, Siberia, Iceland and Greenland this Friday evening (morning hours Saturday 2/5), and there’s a possibility that later tonight, folks in Canada and possibly the northern U.S. might see some auroral action as well. A gust of solar wind streaming from a hole in the sun’s outer atmosphere plus an ejection of gas that occurred late January are behind the activity. The Kp-index for this storm is currently at 5 which is ‘minor storm’. To learn more about the index, click HERE. For the very latest forecast, check out NOAA’s Space Weather Now.
As always, things can change quickly when it comes to the aurora. While this isn’t a big storm, it’s possible those living in the northern U.S. with clear skies might see at least a glowing, green auroral arch low in the northern sky. Worth a look, I’d say. A pity we’re cloudy in Duluth at the moment. The best time to be on the lookout will be late tonight, probably between 10 p.m. and dawn.
