Highlights of Solar and Geomagnetic Activity
21 - 27 March 2022
Solar activity reached moderate levels at 25/0526 UTC due to an
M1/1f flare from Region 2974 (S18, L=090, class/area Cso/90 on 23
Mar). Type II (estimated shock velocity of 959 km/s) and Type IV
radio sweeps were observed with this event. A subsequent CME
signature was first observed in SOHO/LASCO C2 imagery beginning at
25/0548 UTC. Analysis and modeling of the CME suggested an
Earth-directed component with an anticipated arrival on 27 Mar.
Solar activity reached low levels on 22-24 and 26-27 Mar. Very low
levels were observed on 21 Mar.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels.
Geomagnetic field activity reached active levels late on 27 Mar due
to positive-polarity CH HSS influence. Quiet to unsettled levels
were observed on 22, 24-26 Mar. Quiet conditions prevailed on 21 and
23 Mar.
Forecast of Solar and Geomagnetic Activity
28 March - 23 April 2022
Solar activity is likely to be low, with a slight chance for R1-R2
(Minor-Moderate) radio blackouts, 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 04-07 Apr, with moderate levels
expected during the remaining portion of the period.
Geomagnetic field activity is likely to reach G1 (Minor) storm
levels on 28 Mar due to combined CME and CH HSS effects. Active
levels are expected on 03, 20-21 Apr due to recurrent CH HSS
influence. Quiet to unsettled levels are anticipated throughout the
remainder of the outlook period.
