Here is this week's space weather and geophysical report, issued 2021 Mar 22 0107 UTC.

Highlights of Solar and Geomagnetic Activity 15 - 21 March 2021

Solar activity was very low throughout the reporting period. Region 2808 (N19, L=035, class/area, Cao/30 on 12 Mar), Region 2810 (N18, L=307, class/area, Hax/50 on 17 Mar), and Region 2811 (N21, L=248, class/area, Bxo/10 on 21 Mar) all produced low level B-class flare activity. The largest event was a B3 flare from Region 2808 at 16/2026 UTC. No Earth-directed CMEs were observed in available imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 15-19 and 21 Mar, with moderate levels observed on 20 Mar.

Geomagnetic field activity reached G2 (Moderate) geomagnetic storm levels on 20 Mar, with G1 (Minor) storm levels on 21 Mar due to recurrent, negative-polarity CH HSS activity. Unsettled conditions were observed on 15 and 19 Mar. Quiet levels were observed for the remainder of the reporting period (16-18 Mar).

Forecast of Solar and Geomagnetic Activity 22 March - 17 April 2021

Solar activity is expected to be very low, with a slight chance for C-class flare events, throughout the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 22-26, 30-31 Mar, and 01-13, 17 Apr. Moderate levels are expected during the remainder of the outlook period (27-29 Mar, 14-16 Apr).

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 22, 28-30 Mar and 10, 16-17 Apr, with active conditions likely on 23-24 Mar, 02, 08-09 Apr due to recurrent CH HSS activity. Quiet to unsettled levels are anticipated throughout the remainder of the outlook period.
