    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.
