Happy Autumnal Equinox

Happy autumnal equinox today for northern hemisphere residents

 (vernal for those in the southern)
occurs @ 10:49AM EDT/14:49UT

 At 14:49 UTC, 2012 is the earliest the September Equinox has occurred since 1896, but will be beaten by 28 minutes in 2016!      

Region 1573 reappeared yesterday after two days without visible spots
All groups decreased in size yesterday. The largest region is still region 1575 and is still a EKO Beta type group.
No C class solar flares took place yesterday. The largest solar flare was a B8 peaking at 1221z from region 1573. Only occasional C class solar flares are expected today

There is a large 'active region' that is about 6 days away before rotating into view as seen from Earth that is producing large solar flares and coronal mass ejections. See images below from STEREO. Solar flare is circled

This Image shows you a really strong Flare from  the same region happend on Thursday . We know this is the old know region 1564.
