A Short Summary of Carrington Rotation 2204

Carrington Rotation 2204 covered the time period from 2018-05-16 1054 UT – 2018-06-09 2038 UT.
193 Images/Observations were submitted at the time of this writing. The submissions can be viewed in ALPO’s Solar Archive for CR2204:

Even tough the previous rotation only had 9 spotless days, and CR2204 accounted for 12, the Total Active Region Area for the rotation went up from 660 millionths to 770 millionths. This increased activity was mainly caused by AR2712. During the Rotation, the Sun accounted for a total of 3 C-class flares as well as 77 B-class flares, leaving the overall Solar Activity Very Low. We were able to observe three Active Regions, AR2710, AR2711 and AR2712. AR2710 and 11 were both short lived regions (4 and 5 days), but AR2712 lasted for 12 days at which time it did rotate to the far side, and accumulated a Total Region Area of 540 millionths. The Total Active Region size for the rotation went up from 660 for the previous rotation, to 770 millionths, and the maximum sunspots count was 12 on three days, May 26, May 30th and June 2nd. The rotation ended with spotless day 227.

For this rotation we would like to feature some images submitted by three of our observers, Christian Viladrich, Monty Leventhal, and Frank Melillo. Thanks to them, as well as all other contributors for another great rotation. Please take a look at all the drawings/images by clicking on the link above which links to our archive for CR2204.
