Highlights of Solar and Geomagnetic Activity
08 – 14 March 2021

Solar activity was very low on 08 and 10-14 Mar. Low levels of solar
activity were observed on 09 Mar due to a C1 flare at 09/1235 UTC,
from Region 2808 (S19, L=035, class/area, Cao/30 on 12 Mar). 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 08-12 and 14 Mar, with moderate levels observed on 13
Mar.

Geomagnetic field activity reached G1 (Minor) geomagnetic storm
levels on 14 Mar, with active levels on 13 Mar due to recurrent,
negative-polarity CH HSS influence. Quiet to unsettled conditions
were observed for the remainder of the reporting period (08-12 Mar).

Forecast of Solar and Geomagnetic Activity
15 March – 10 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 15-16, 20-27, 30-31 Mar and 01-10
Apr. Moderate levels are expected during the remainder of the
outlook period (17-19, 28-29 Mar).

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic
storm levels on 28-30 Mar and 10 Apr, with active conditions likely
on 15, 19-21 Mar and 09 Apr due to recurrent CH HSS activity. Quiet
to unsettled levels are anticipated throughout the remainder of the
outlook period.
