Here is this week's space weather and geophysical report, issued 2022 Jan 10 0129 UTC.

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.
