Highlights of Solar and Geomagnetic Activity 07 - 13 December 2020
Solar activity was reached low levels on 07 Dec due to a long-duration C7/1f flare observed at 07/1632 UTC from Region 2790 (S22, L=252, class/area=Hsx/80 on 10 Dec). The associated halo CME arrived at Earth just after 10/0000 UTC as an interplanetary shock, and with the driver directed south of the ecliptic plane. Solar activity was at very low levels throughout the remainder of the period with B-class flare activity.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was normal to moderate throughout the period.
The geomagnetic field reached active levels early on 10 Dec due to the arrival of the 07 Dec CME. Quiet or quiet to unsettled conditions were observed throughout the remainder of the period.
Forecast of Solar and Geomagnetic Activity 14 December - 09 January 2021
Solar activity is expected to be very low to low throughout the outlook period.
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 21-25 Dec, with normal to moderate levels expected to persist throughout the remainder of the outlook period.
Geomagnetic field activity is expected to reach active levels on 20-22 Dec due to CH HSS influences. Quiet and quiet to unsettled conditions are expected to prevail throughout the remainder of the period.
