A Short Summary of Carrington Rotation 2226

Carrington Rotation CR2226 covered the time period from 2020-01-06 0911 UT – 2020-02-02 1721 UT.
At the time of this writing 208 images were submitted for the archives. The submissions can be viewed in ALPO’s Solar Archive for CR2226 which can be accessed at:

The rotation brought us three active regions, AR2755, AR2756 and AR2757, of which one was reversed polarized. In addition to this AR, we had additional reversed polarized areas which lasted days, or just a few hours. See our overview (pdf) of the Reverse Polarized Areas, by clicking here. AR2757, a cycle 24 area, finally brought an Active Region Area again with a size of 100 millionths, while it was reported as an Hsx area. The last time we saw an area over 100 millionths was AR2745 on May 19, 2019. The highest Wolf number was 18 on January 27th, and the Total Rotation Active Region Area was at 430 millionth. Overall Solar Activity remained Very Low and the rotation increased the spotless days count since solar maximum to 662. Finally, during the period SWPC reported 2 A-class, 5 B-class, and no C-class flares.
This time we would like to feature 3 images submitted by Howard Eskildsen, Theo Ramakers and Jeffrey Carels. Thanks to these and all other observers for submitting their observations Please click the thumbnails below to see the full images in the archive.
