The K7RA Solar Update 12/11/2020 Tad Cook, K7RA, Seattle, reports: Solar activity quieted this week, with the average daily sunspot number declining from 57.6 to 28.9, and the average daily solar flux softening from 108.1 to 91.9. On December 8 – 10, the sunspot number was 11 on each day, which is the minimum non-zero sunspot number. Sunspot group 2786 provided some great activity, but it is about to rotate off the sun’s visible surface. But a look at STEREO satellite images on Thursday night (December 10) shows some magnetic complexity about to became geo-effective from the sun’s southern hemisphere. This could mean more great conditions. The average daily planetary A index went from 6.4 to 4.4, and average daily middle latitude A index went from 5.6 to 3.1.
