    Highlights of Solar and Geomagnetic Activity
    03 - 09 February 2025

    Solar activity reached high levels. Region 3981 (N07, L=341,
    class/area=Ekc/430 on 05 Feb) was the most active region on the
    disk. AR 3981 produced an M8.8 flare at 03/0358 UTC, the largest
    event of the period, in addition to several R1 and R2 events
    throughout the course of the week. No Earth-directed CMEs were
    observed.

    No proton events were observed at geosynchronous orbit.

    The greater than 2 MeV electron flux at geosynchronous orbit was at
    normal to moderate levels throughout the week.

    Geomagnetic field activity reached active levels on 08 Feb, and G1
    (Minor) levels on 09 Feb, due to a SSBC followed by the onset of
    negative polarity CH HSS influences. Quiet and quiet to unsettled
    conditions were observed throughout the remainder of the period.

    Forecast of Solar and Geomagnetic Activity
    10 February - 08 March 2025

    Solar activity is likely to reach moderate to high levels throughout
    the period. R1-R2 (Minor-Moderate) events are likely, with a slight
    chance for R3 or greater events.

    No proton events are expected at geosynchronous orbit, barring
    significant flare activity.

    The greater than 2 MeV electron flux at geosynchronous orbit is
    expected to be at normal to moderate levels.

    Geomagnetic field activity is expected to reach G1 (Minor) storm
    levels on 10, 13, and 28 Feb, and active levels are expected on
    11-12 Feb, and 01 Mar due to CH HSS influences. Quiet and quiet to
    unsettled conditions are likely to prevail throughout the remainder
    of the period.
