    Highlights of Solar and Geomagnetic Activity
    28 February - 06 March 2022

    Solar activity ranged from very low to moderate levels throughout
    the week. The largest event of the period was an M2/1b flare
    observed at 02/1739 UTC from Region 2958 (N17, L=035,
    class/area=Bxo/60 on 03 Mar). Regions 2957 (S16, L=038,
    class/area=Dai/240 on 05 Mar) and 2960 (S20, L=335,
    class/area=Dki/450 on 05 Mar) were the most active regions
    throughout the week, but produced only C-flares. Multiple DSFs were
    detected during the summary period, however, none were expected to
    be Earth-directed.

    No proton events were observed at geosynchronous orbit.

    The greater than 2 MeV electron flux at geosynchronous orbit reached
    high levels on 06 Mar, with normal to moderate levels observed
    throughout the remainder of the week.

    Geomagnetic field activity reached active and minor (G1) storm
    levels on 05-06 Mar due to the influence of a series of negative
    polarity CH HSSs. Quiet and quiet to unsettled conditions were
    observed throughout the remainder of the summary period.

    Forecast of Solar and Geomagnetic Activity
    07 March - 02 April 2022

    Solar activity is expected to be very low throughout the period,
    with C-flares likely and a chance for M-flares.

    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 07-10, 20-23 Mar, and 02 Apr.
    Normal to moderate levels are expected throughout the remainder of
    the outlook period.

    Geomagnetic field activity is expected to reach minor (G1) storm
    levels on 01-02 Apr, and active levels on 11-12, 19-21, and 31 Mar
    in response to multiple CH HSSs moving through geoeffective
    position. Quiet and quiet to unsettled conditions are expected to
    prevail throughout the remainder of the period.
