Highlights of Solar and Geomagnetic Activity 09 - 15 November 2020
Solar activity was at very low to low levels during the period. Very low levels were observed on 09 Nov and 13-15 Nov, while low levels occurred on 10-12 Nov. Region 2781 (S23, L=255, class/area Eki/475 on 06 Nov) produced a C1/Sf flare observed at 10/1946 UTC. The C-class activity was observed on 11-12 Nov from new Region 2782 (S31, L=155, class/area Cro/030 on 12 Nov), the largest was a C2/Sf flare observed at 11/1912 UTC. No Earth-directed CME activity was observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 11 Nov with a maximum flux of 2,250 pfu observed at 11/1655 UTC. Normal to moderate levels were observed on 09-10 Nov and 12-15 Nov.
Geomagnetic field activity was quiet throughout the period. A nominal solar wind regime dominated the period with a mostly neutral IMF. Solar wind speeds generally ranged between about 295 km/s to 445 km/s under a predominately negative phi orientation.
Forecast of Solar and Geomagnetic Activity 16 November - 12 December 2020
Solar activity is expected to be very low from 16-27 Nov and 12 Dec. The return of old Region 2781 (S23, L=255) from 28 Nov - 11 Dec is expected to increase solar activity levels to very low to low.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels on 16 - 20 Nov and again on 29 Nov - 12 Dec. High levels are expected from 21-28 Nov due to recurrent CH HSS influence.
Geomagnetic field activity is expected to be at quiet to unsettled levels on 21 - 25 Nov and again on 03-04 Dec due to recurrent CH HSS influence. Active intervals are possible on 22, 24 and 25 Nov. Mostly quiet conditions are expected to prevail for 16-20 Nov, 26 Nov - 02 Dec and 05-12 Dec.
