Here is this week's space weather and geophysical report, issued 2021 Mar 08 0146 UTC.

Highlights of Solar and Geomagnetic Activity 01 - 07 March 2021

Solar activity was very low on 01 and 03-07 Mar. Low levels of solar activity were observed on 02 Mar due to a C1/Sf flare at 02/0003 UTC from Region 2807 (S18, L=154, class/area=Cro/30 on 04 Mar). No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was moderate on 01-02 Mar, with high levels observed on 03-07 Mar.

Geomagnetic field activity reached G2 (Moderate) geomagnetic storm conditions on 01 Mar, and G1 (Minor) storm conditions on 02-03 Mar, due to negative polarity CH HSS influence. Active conditions were observed on 04, and 06-07 Mar due to CH HSS influence. Quiet conditions prevailed on 05 Mar.

Forecast of Solar and Geomagnetic Activity 08 March - 03 April 2021

Solar activity is expected to be very low-to-low 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 08, 20-27 Mar, and 30 Mar- 03 Apr. Moderate flux levels are expected throughout the remainder of the outlook period.

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storms on 18-19 Mar, with active conditions likely on 12-13, 15, 20-21, and 29-30 Mar, due to the influence of multiple CH HSSs.
