The first of several CMEs en route to Earth struck our planet’s magnetic field on Sept. 9th around 1130UT. The impact sparked a strong (Kp=7) geomagnetic storm, which is now subsiding. Last night Northern Lights were spotted in the United States as far south as Washington, Wisconsin, Michigan,Vermont, Montana, Maine and North Dakota. More geomagnetic activity could be in the offing as one or two more CMEs approach. (SpaceWeather)

A short lived moderate geomagnetic storm took place on Friday due to a incoming CME shock just after 11:00 UTC. Minor storm levels did persist overnight and Aurora was spotted in northern parts of Canada.
Just before 14:00 UTC Saturday, the solar wind jumped from 460 km/s to 520 km/s. Keep an eye on the ACE Spacecraft data for any further increases that may contribute to minor geomagnetic activity. (SolarHam)

The Farside of the Sun has been very active and late Thursday night a large Solar Flare triggered a bright Coronal Mass Ejection. I created a movie below showing the Flare and CME. This was most likely an X-Class event.
