This rotation only showed active regions for 5 days of the rotation, spread over three short periods. AR2703 and AR2704 were visible only for 2 days each and covered 10, resp. 30 millionths. AR2705 was only a one day event and covered only 10 millionths. The highest Wolf Number of 14 was recorded on April 14, which also accounted for the second day of AR2704. The rotation ended with spotless day 206 making the rotation the rotation with the highest spotless count since solar max..

For this rotation we would like to feature three observations submitted by three of our observers, Roberto Braga, Guilherme Grassmann, and Howard Eskildsen. 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 CR2202.
