Northern Lights Tonight??June 28th, 2013 at 9:30 pm by Bill Steffen under Bill's Blog, Weather
The kp index is up to 7 at 2:15 AM. Seeing Aurora in MN, MI, WI, IA, ND, SD, MT. From www.spaceweather.com: “A (Kp=7) geomagnetic storm is underway around the poles. Solar wind conditions favor auroras at high latitudes, although in the northern hemisphere solstice twilight will sharply reduce visibility.” With a five, you might catch a faint aurora on the northern horizon if you are away from artificial light. Wed like that number to be around 7-8 for a better show. Still it’s worth watching. Keep checking the link at spaceweather.com and scroll down and look at the kp number on the left side.
