Solar wind hit Earth's magnetic field

A sharp gust of today, June 17th, at approximately 0230 UT. This probably signaled the arrival of a CME, en route from the sun since June 14th. The impact did not spark a significant geomagnetic storm; bright auroras tonight are unlikely. (SpaceWeather)

Currently the visible solar disk consists of two big sunspot groups 1234 in the south and 1236 in the north. Both are producing C-Class flares and there is a chance for another M-Class event. A third sunspot group will soon rotate into view on the southeast limb and was the source of another C-Class flare early on Thursday. Stay tuned as solar activity is increasing once again.
