Dear Collaborators,
The level of solar activity is very low. The spots that comprised NOAA region 12797 have been re-designated into 2 separate regions. The leading single-polarity spot group retains number NOAA 12797 (classified as an alpha/H-type sunspot group), while the trailing bipolar spot group has been assigned the new number NOAA 12798 (classified as a beta/C-type sunspot group). The C1.4 flare from NOAA 12797 that was mentioned in yesterday's message was actually associated with the magnetic flux that is now designated as NOAA 12798, and this region has continued to produce B-class activity (the largest being a B5.4 flare on 21-Jan-2021 at 09:47 UT). More B-class activity is expected over the following 24-hour period, with a small chance of an isolated low C-class flare.
The position of NOAA 12798 on 21-Jan-2021 at 22:00 UT is:
S17E34 , ( -524", -214" )
