2020 January 26 Sun - AR12757 + possible new active region

AR12757 has been very active in the past 12 hours, with bright flares and filaments. The 2 sunspots are also growing, and may be splitting up into more sunspots.
Watch out on this group.
meanwhile, another new active group shows up on the SE limb, at S30 latitude. This group has demonstrated magnetic reversal, and should belong to the 25th solar cycle.

Sunspot count: group=1, sunspot number=2, R=12
