A coronal mass ejection impact was detected at DSCOVR around 12:40 UTC today. The north-south direction of the interplanetary magnetic field (Bz) flipped southward to about -12nT to -12nT. A minor G1 geomagnetic storm watch is in effect for the remainder of the day.
A lot of people come to SpaceWeatherLive to follow the Solar activity or if there is a chance to see the aurora, but with more traffic comes higher costs to keep the servers online.
