Solar update: Geomagnetic disturbance/large solar flare

Near X-Flare Detected
Departing sunspot 1996 produced an impulsive M9.3 solar flare peaking at 22:34 UTC. Rapid releases of energy are not generally known to produce large coronal mass ejections, but we will wait for updated coronagraph imagery to confirm if a plasma cloud is associated. If there is, it would likely be directed mostly away from our planet. Click HERE for a movie. Imagery below by SDO/EVE.

Solar Update / Brief Geomagnetic Storm
Good morning. Below is an updated look at the visible solar disk on Thursday. Solar activity reached high levels. The strongest event during the past 24 hours was an impulsive M9.3 solar flare around sunspot 1996 at 22:34 UTC. The event did not generate a noteworthy CME. The active region continues to rotate behind the west limb and out of direct Earth view. All other visible regions, including sunspots 2002 and 2003 remain stable for now. A couple of small trailing spots behind region 2005 near the northeast limb are now coming into view but appear to be rather insignificant. There will remain a chance for an isolated moderate solar flare during the next 24 hours.
A brief period of minor G1 level geomagnetic storming was observed last night at high latitudes during a prolonged period of southward Bz. Conditions have since returned to more quieter levels.
Stay tuned to for the latest information.
