Highlights of Solar and Geomagnetic Activity
07 - 13 September 2020

Solar activity was very low throughout the reporting period. No
spotted regions were observed on the visible disk and no
Earth-directed CMEs were observed in available coronagraph imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was
normal to high levels throughout the reporting period. GOES-16 peak
flux reached 10,200 pfu at 07/1600 UTC.

Geomagnetic field activity was quiet to unsettled under a mostly
nominal solar wind regime.

Forecast of Solar and Geomagnetic Activity
14 September - 10 October 2020

Solar activity is expected to be at very low levels for the outlook
period.

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 on 14 - 25 Sep and at
high levels, following CH HSS activity, from 26 Sep - 10 Oct.

Geomagnetic field activity is likely to range from quiet to G1
(Minor) geomagnetic storm levels. G1 levels are likely on 27 Sep;
active levels are likely on 25-26 Sep and 28 Sep; unsettled levels
are likely on 23-24 Sep and 29 Sep. All elevated levels of
geomagnetic activity are in response to anticipated CH HSS
influence. The remainder of the outlook period is expected to
observe quiet conditions.
