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 to be on 27 September, and 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.
