Highlights of Solar and Geomagnetic Activity
03 - 09 January 2022
Solar activity was at very low to low levels during the period.
C-class activity was observed on 06-07 Jan from Region 2924 (S31,
L=038, class/area Ehi/430 on 08 Jan). The largest of these events
was a C2 flare observed at 07/2210 UTC. The remaining regions were
unremarkable and quiet. Late on 09 Jan, Type II (575 km/s S.V.) and
Type IV radio emissions were observed, most likely associated with
CME activity at or behind the NE limb. No other activity was
observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 08 Jan with a maximum flux of 2,655 pfu obseved at
08/1805 UTC. Moderate levels were observed on 03-07 Jan and 09 Jan.
Geomagnetic field activity ranged from quiet to GI (Minor) storm
levels. Quiet to unsettled levels were observed on 03-04 Jan, with
active periods on 04 Jan, due to positive polarity CH HSS influence.
Quiet levels persisted on 05 Jan through late on 08 Jan. G1 (Minor)
storm levels were observed late on 08 Jan due to negative polarity
CH HSS influence. Quiet to unsettled levels were observed on 09 Jan
as CH HSS influence slowly waned.
Forecast of Solar and Geomagnetic Activity
10 January - 05 February 2022
Solar activity is expected to be at very low to low levels through
the outlook period. A slight chance to a chance for M-class flare
activity (R1-R2, Minor to Moderate) is possible on 10-29 Jan due to
the return of old Regions 2916 and 2918.
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 19-23 Jan due to recurrent CH HSS
influence. Moderate levels are expected on 10-18 Jan, 24 -31 Jan and
01-05 Feb.
Geomagnetic field activity is expected to be at unsettled levels on
10, 16-18, 23-26, 28-30 Jan and 04-05 Feb with active levels
expected on 17 Jan and 04 Feb, all due to recurrent CH HSS activity.
