A short Summary of Carrington Rotation 2192

Carrington Rotation 2192 covered the time period from 2017-06-23 0117 UT – 2017-07-20 0606 UT.
Solar Activity increased again, and so did the number of submissions. 495 Submissions were added to the archive at the time of this summary, and can be viewed in ALPO’s Solar Archive for CR2192:

During the rotation we could observe 5 regions, one of which, AR2667, lasted only one day. The rotation started on 2017-06-23 with 2 Active Regions and a Wolf number of 23. The total Active Region Area was 80 millionths. The highest Wolf Number of 58 was reached on 2017-07-23, while AR2665 was the dominant Active Region. AR 2665 also claimed to be the largest Active Region area for the rotation on 7/10 with 710 millionths (a coincidence?). The rotation had a period of 3 spotless days 0n 7/4 and 7/5 as well as a single day on 7/19, bringing the total spotless days since Solar Maximum to 80. The rotation ended with a spotless Sun.
For this Rotation we would like to feature three observations 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 their images by clicking on the link above linking to our archive for CR2192.
Clear Skies,
Theo Ramakers
