Short Summary of Carrington Rotation CR2236

Carrington Rotation CR2236 covered the time period from 2020-10-05 0018 UT until 2020-11-01 0720 UT.
The observations can be viewed in my Solar Archive for CR2236 which can be accessed at: http://ceastronomy.org/gallery/main.php?g2_itemId=51354
The rotation brought us 5 spotless days,  We could observe 6 Active Regions, all of which were Cycle 25 polarized.   The smallest one, AR2777, was very unstable and did not make it over 10 millionths during its one day of being active. AR 2776 lasted the longest with 12 days, as it rotated from the Eastern limb and disappeared around the Western limb.  Total Active Region Area for AR2776 was 420 millionths with the maximum daily area of 110 millionth on October 19th. AR2778 however, which developed much faster, accounted for 830 millionths for its short appearance in CR2236 of the Total Active Region Area for the Rotation of 2000 millionths. Overall Solar Activity is ticking up a little, while the rotation increased the spotless days count since solar maximum to 856 spotless days. Finally, during the period SWPC reported 2 A-class, 82 B-class flares,  and 14 C-class flares.

This time I would like to feature some Ha images showing AR2776 on three consecutive days from October 17 through 19, during a time that some of the flares showed as “Ellermans bombs”.
Clear Skies,
