    Highlights of Solar and Geomagnetic Activity
    01 - 07 April 2024

    Solar activity reached moderate levels on 01 Apr due to an M3.9/Sf
    flare at 01/0132 UTC from Region 3625 (N13, L=174, class/area=Dai/80
    on 01 Apr); the largest event of the period. The remainder of the
    period saw low level solar activity with C-class flares observed
    from several unremarkable active regions. No Earth-directed CMEs
    were observed as a result of this periods activity.

    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 period.

    Geomagnetic field activity reached active levels on 01 Apr, and
    unsettled levels on 02-03 Apr, due to weak positive polarity CH HSS
    influences. Active conditions were observed again on 04 Apr, with
    unsettled levels observed on 05-06 Apr, due to weak negative
    polarity CH HSS influences. Quiet conditions and a nominal solar
    wind environment prevailed over 07 Apr.

    Forecast of Solar and Geomagnetic Activity
    08 April - 04 May 2024

    Solar activity is expected to be at low to moderate levels
    throughout the outlook period, with C-class flare activity expected
    and a varying chance for M-class flare activity.

    No proton events are expected at geosynchronous orbit.

    The greater than 2 MeV electron flux at geosynchronous orbit is
    expected to continue at normal to moderate levels through 04 May.

    Geomagnetic field activity is expected to reach active levels on
    09-10 Apr in response to anticipated positive polarity CH HSS
    influence. Quiet and quiet to unsettled conditions are expected to
    prevail throughout the remainder of the outlook period.
