    Highlights of Solar and Geomagnetic Activity
    24 - 30 October 2022

    Solar activity was at low levels during the period. Weak to moderate
    levels of C-class activity was observed from Regions 3126 (S10,
    L=233, class/area Dai/160 on 25 Oct), 3130 (S25, L=185, class/area
    Dao/090 on 27 Oct), 3131 (N23, L=111, class/area Cso/190 on 27 Oct),
    3133 (N26, L=095, class/area Dao/140 on 28 Oct) and 3135 (N27,
    L=063, class/area Eao/160 on 30 Oct). No Earth-directed CMEs were
    detected during the period.

    No proton events were observed at geosynchronous orbit.

    The greater than 2 MeV electron flux at geosynchronous orbit was at
    normal to moderate levels on 24-29 October. High levels were
    observed on 30 Oct with a peak flux of 3,715 pfu observed at 30/1735

    Geomagnetic field activity was at quiet to G1 (Minor) storm levels
    during the period. Quiet to unsettled levels were observed from
    24-27 October. Activity levels increased to unsettled to active on
    28 October, unsettled to G1 (Minor) storm levels on 29 October and
    quiet to active levels on 30 October. The increase in activity on
    28-30 October was due to positive polarity coronal high speed stream

    Forecast of Solar and Geomagnetic Activity
    31 October - 26 November 2022

    Solar activity is expected to be at very low to low levels on 31 Oct
    - 02 Nov and 18 - 26 Nov. There is a slight chance for M-class
    activity on 03 - 17 Nov due to the return of previously active
    regions with M-class flare history.

    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 31 Oct - 09 Nov and 26
    Nov. Low to moderate levels are expected on 10 - 25 Nov.

    Geomagnetic field activity is expected to be at unsettled to active
    levels on 31 Oct - 06 Nov, 10-12 Nov, 18-19 Nov and 24-26 Nov. G1
    (Minor) geomagnetic storm levels are possible on 05, 18 and 25 Nov.
    This elevated level of activity is in anticipation of mulitple,
    recurrent CH HSSs. The remainder of the outlook period is likely to
    be at mostly quiet levels.
