Here we go again! NOAA SWPC has issued another storm watch for a G3 level geomagnetic event. Right now, we’re already at G2 level. My guess is that we’ll hit G3 if the interplanetary magnetic field turns southward, so keep an eye on the real-time solar wind conditions. Because the storm has already started, I doubt that this will drive any visible aurora over the United States- by the time nightfall hits, the storm will have subsided again. But keep your eyes peeled just in case.
Check out my previous storm watch post for an idea of what values to watch as the storm progresses.
