A Short Summary of Carrington Rotation 2196

Carrington Rotation 2196 covered the time period from 2017-10-10 0008 UT – 2017-11-06 0713 UT.
261 Submissions were added to ALPO’s Solar archive at the time of this summary despite the very low solar activity. The submissions can be viewed in ALPO’s Solar Archive for CR2196:

During the rotation, we could observe 3 Active Regions AR2684-AR2686 of which AR2684 was only visible for one day. The highest Wolf Number of 23 was recorded on five days, 10/24 and 10/25, 10/27 and 10/28 and 10/30 while the highest total Active Region Area for the day of 90 millionths was recorded on 10/24 and 10/25th. The largest region for the rotation was AR2685 covering an area of 70 millionths on 10/23. This was so far the least active region since Solar Maximum with the Total Active Region Areas for the rotation of 540 millionths and 16 spotless days. The last full day of the rotation was spotless, for spotless day 107.

For this Rotation we would like to feature three observation drawings by three of our observers, Tony Broxton, Monty Leventhal, and Joe Gianninoto. Thanks to them, as well as all other contributors for another great rotation. Please take a look at all drawings/images by clicking on the link above linking to our archive for CR2196.
