Sunspot Summary Carrington Rotation 2105 – Howard Eskildsen

Sunspot Summary Carrington Rotation 2105
Observations in Ca-K
Start date: 2010/12/24, 01:06 UT, End date: 2011/01/20, 09:10 UT,http:bass2000.obspm.fr/ephem.php?lang=en
per Howard Eskildsen

Notes:
The sun had been without spots for the last 5 days of CR 2104 and the next spots appeared on the second day of the rotation. Both dimuitive spots only lasted two days. Only two of the 13 spots of the rotation were large and persistent. The others were small and relatively short lived. The sun was totally blank for two days during the latter part of the rotation. It ended with the large spot group, AR 1147, showing some complexity, but little activity.
