Strong Solar Flare from 1429 sunspot

Sunspot 1429 just generated another Coronal Mass Ejection and is seen in the latest Lasco C2 images. This explosion was much smaller than the event from last night, but should be a sign of things to come.

The Kp Index is creeping very close to the G1 Geomagnetic Storm Level. The Bz component of the Interplanetary Magnetic Field is tipped sharply south and combined with a gusty solar wind, Aurora at high latitudes will be possible tonight.

The solar wind speed has shown a gradual increase today. This gradual increase is expected to continue over the next 24-48 hours due to a solar sector boundary crossing. Minor geomagnetic activity will be possible at high latitudes.
