Highlights of Solar and Geomagnetic Activity
21 - 27 December 2020
Solar activity was at very low levels from 21-27 Dec. The largest
flare observed was a B7.3 from Region 2795 (S18, L=318, class/area
Dao/200 on 24 Dec) on 24 Dec. No Earth-directed CMEs were 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 24-27 Dec due to CH HSS influence. Normal
to moderate levels were observed on 21-23 Dec.
Geomagnetic field activity reached active levels on 21 and 23 Dec,
and unsettled levels on 22, 24-25 Dec, all due to positive polarity
CH HSS influences. Quiet levels were observed on 26-27 Dec.
Forecast of Solar and Geomagnetic Activity
28 December - 23 January 2021
Solar activity is expected to be at very low levels throughout the
period with a slight chance for low levels on 28 Dec - 04 Jan, and
17-23 Jan due to the flare potential from Region 2795 (S18, L=318,
class/area Dao/200 on 24 Dec).
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate to high levels on 28-29 Dec and 20-23 Jan
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 be at unsettled to active
levels on 5-6 Jan and 18-20 Jan, and quiet to unsettled levels on 29
Dec, 3 Jan, and 21 Jan, all due to recurrent CH HSS influences.
Mostly quiet levels are expected on the remaining days in the
outlook period.
