The K7RA Solar Update 03/05/2021
Tad Cook, K7RA, Seattle, reports: We saw one day during the February 25 – March 3 reporting week Monday, March 1 with no sunspots, so the average daily sunspot number declined slightly from 19.6 to 18.9. Two new sunspot groups (2806 and 2807) appeared on Tuesday, March 2.
Average daily solar flux increased only slightly during the reporting week, from 75.7 to 76.7.
Average daily planetary A index softened slightly from 16 to 14.7, and the middle latitude average went from 12.4 to 10.4. Geomagnetic indicators remained somewhat active due to persistent solar wind. The most active day was Monday, when Alaska’s high-latitude College A index reached 34.
Spaceweather.com reported a G2 class geomagnetic storm on Monday, aided by a significant crack in Earth’s magnetic field. Although activity was otherwise moderate this week, the March 1 event was the largest storm since a G3 event 94 weeks earlier, on May 14, 2019.
