M6.5 Solar Flare + CME HD

Best viewed with window expanded
The strongest solar flare in quite some time took place within the past couple of hours around Sunspot 1719. The moderately strong event measuring M6.5 took place at 07:16 UTC. A Coronal Mass Ejection (CME) is now visible in the latest STEREO Ahead and STEREO Behind COR2 imagery. Because 1719 is now squarely facing Earth, the plasma should be directed this way. This will raise the chances of geomagnetic storming by this weekend.
Geomagnetic Storm Watch
The Geomagnetic Field is currently at quiet levels. Things should change drastically heading into the weekend. A Geomagnetic Storm watch has been issued by NOAA Space Weather Prediction Center for early on April 13th as a Coronal Mass Ejection is expected to sweep past Earth. Moderate G2 Level with a chance for Strong G3 Level Storming will be possible at high latitudes. Sky Watchers should be alert for visible aurora once the cloud arrives.
