Highlights of Solar and Geomagnetic Activity
30 August – 05 September 2021

Solar activity was at low levels. Region 2860 (S29, L=01, class/area
Eac/240 on 30 Aug) was the most active region on the disk producing
several C-class flares. The largest flare was a C3.0/SN optical at
30/2134 UTC from Region 2860. No notable CME activity was observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
moderate to high levels on 30 Aug-03 Sep, 05 Sep. Normal to moderate
levels were observed on 04 Sep.

Geomagnetic field activity was at quiet to unsettled levels on 30-31
Aug, 03 Sep, and 05 Sep. Quiet levels were observed on 01-02 Sep,
and 04 Sep.

Forecast of Solar and Geomagnetic Activity
06 September – 02 October 2021

Solar activity is expected to be at low levels with a slight chance
for M-class activity on 16-29 Sep due to the possible return of
Region 2860. The remainder of the highlight period is expected to be
at very low to low levels.

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 from 06-23 Sep. Moderate
to levels are expected on 24 Sep-02 Oct due to recurrent coronal
hole high speed stream influences.

Geomagnetic field activity is expected to be at quiet to unsettled
levels with a chance for active levels on 21 Sep and 02 Oct due to
recurrent CH HSS influences. Quiet levels are expected for the
remainder of the outlook period.
