A Short Summary of CR2227

Carrington Rotation CR2227 covered the time period from 2020-02-02 1721 UT – 2020-03-01 0126 UT.
At the time of this writing 118 images were submitted for the archives, which is about 100 less than for the previous rotation, and is a result of being around solar minimum and the bad weather conditions. The submissions can be viewed in ALPO’s Solar Archive for CR2227 which can be accessed at:
http://alpo-astronomy.org/gallery3/index.php/Solar-Observations-Archive/SolarImages2020/CR2227
The rotation did not bring us any new active regions, however, on the fist day AR2757 turned to the far side of the Sun. We noticed some small areas of which a few were reverse polarized, which did not create any Sunspots, . See our overview (pdf) of the Reverse Polarized Areas, by clicking here. On March 3rd. the spotless streak stands at 28 spotless days which gives this solar minimum 6 streaks of 28 days or higher, whereas the previous solar minimum gave us only 3. However, these 3 spotless streaks were much longer than what we have seen so far. Overall Solar Activity remained Very Low and the rotation increased the spotless days count since solar maximum to 690. Finally, during the period SWPC reported 3 A-class, and no B- or C-class flares.
This time we would like to feature 3 images submitted by Howard Eskildsen, Theo Ramakers and Guilherme Grassman. Thanks to these and all other observers for submitting their observations Please click the thumbnails below to see the full images in the archive.

A Short Summary of Carrington Rotation 2226

Carrington Rotation CR2226 covered the time period from 2020-01-06 0911 UT – 2020-02-02 1721 UT.
At the time of this writing 207 images were submitted for the archives. The submissions can be viewed in ALPO’s Solar Archive for CR2226 which can be accessed at:
http://alpo-astronomy.org/gallery3/index.php/Solar-Observations-Archive/SolarImages2019/CR2226
The rotation brought us three active regions, AR2755, AR2756 and AR2757, of which one was reversed polarized. In addition to this AR, we had additional reversed polarized areas which lasted days, or just a few hours. AR2757, a cycle 24 area, finally brought an Active Region Area again with a size of 100 millionths, while it was reported as an Hsx area. The last time we saw an area over 100 millionths was AR2745 on May 19, 2019. The highest Wolf number was 18 on January 27th, and the Total Rotation Active Region Area was at 430 millionth. Overall Solar Activity remained Very Low and the rotation increased the spotless days count since solar maximum to 662. Finally, during the period SWPC reported 2 A-class, 5 B-class, and no C-class flares.

This time we would like to feature 3 images submitted by Howard Eskildsen, Theo Ramakers and Jeffrey Carels. Thanks to these and all other observers for submitting their observations Please click the thumbnails below to see the full images in the archive.

The Carrington event of September2, 1859!

From Spaceweather- September 2nd, 2015

Today is the anniversary of an historic solar storm, the Carrington Event. On Sept. 2, 1859, a CME struck Earth’s magnetic field with such power that telegraph stations caught fire and people in Cuba read their morning newspapers by the red light of the aurora borealis. If a similar storm struck our planet today, it might cause trillions of dollars of damage to society’s high-tech infrastructure. Could the Carrington Event happen again? It almost did just a few years ago. Extreme solar storms–past, present and future–are highlighted on today’s edition of http://spaceweather.com
