Highlights of Solar and Geomagnetic Activity
15 - 21 November 2021

Solar activity was at very low levels with only B-class activity
observed. No Earth-directed CMEs were observed in LASCO coronagraph
imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 15 Nov due to CH HSS influences. Normal to moderate
levels were observed on 16-21 Nov.

Geomagnetic field activity reached active levels on 15-17 Nov due to
CH HSS influences. Quiet to unsettled levels were observed on 18-21
Nov.

Forecast of Solar and Geomagnetic Activity
22 November - 18 December 2021

Solar activity is expected to be at low levels on 30 Nov - 14 Dec
due to the expected return of Regions 2894 (S27, L=85, class/area
Dao/130 on 12 Nov) and 2895 (N24, L=73, class/area Dso/130 on 10
Nov). Very low levels are expected on 22-29 Nov, and 15-18 Dec.

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 10-12 Dec due to recurrent CH HSS
influences. Normal to moderate levels are expected for the remainder
of the outlook period.

Geomagnetic field activity is expected to reach unsettled to active
levels on 27 Nov and 12-14 Dec due to recurrent CH HSS influences.
Quiet to unsettled levels are expected for the rest of the outlook
period.
