    Highlights of Solar and Geomagnetic Activity
    10 - 16 February 2025

    Solar activity reached moderate levels on 10-11 and 13-14 Feb, with
    low levels of activity observed on 12 and 15-16 Feb. In total, six
    M1 flares (R1-Minor) were observed throughout the week from Regions
    3981 (N07, L=341, class/area=Esi/190 on 10 Feb), 3990 (S10, L=191, class/area=Dki/310 on 14 Feb), and 3992 (S06, L=243,
    class/area=Dai/210 on 13 Feb).

    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 10 Feb, with high levels observed on
    11-16 Feb.

    Geomagnetic field activity reached G1 (Minor) levels on 10 and 14-15
    Feb, and active levels on 11-13 and 16 Feb, due to negative polarity
    CH HSS influences.

    Forecast of Solar and Geomagnetic Activity
    17 February - 15 March 2025

    Solar activity is expected to range from low to moderate levels
    throughout the period. There is a varying chance for R1-R2
    (Minor-Moderate) events, and 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
    likely to reach high levels on 18-19 and 23 Feb, and 10-15 Mar.
    Normal to moderate levels are likely to prevail throughout the
    remainder of the period.

    Geomagnetic field activity is likely to reach G1 (Minor) levels on
    28 Feb, 09 and 12-14 Mar, with active levels likely on 17-18 Feb,
    and on 01 and 15 Mar, due primarily to CH HSS influences. Quiet and
    quiet to unsettled conditions are expected to prevail throughout the
    remainder of the period.
