Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 7 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (25 Mar, 26 Mar, 27 Mar). IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 672 km/s at 23/2150Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 11906 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (25 Mar, 26 Mar) and quiet to unsettled levels on day three (27 Mar). III.
