Astro Tours Posted December 1, 2020 Share Posted December 1, 2020 Yesterday the sun launched it largest solar flare in 3 years with a M4.4 event that initially wasn't thought to be Earth facing. However it's possible that a CME might now sideswipe Earth's magnetic field on Dec. 1-2, according to NOAA analysts. The glancing blow, if it occurs, is expected to cause no more than G1 geomagnetic storms, but hey its better than nothing. Sunspot region 2786 has only just starting to rotate onto the earth-facing disk so it is hard to say if there are more sunspots hiding behind the limb but there is at least one very large sunspot associated with this sunspot region.
