IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z

Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M3 event observed at 01/0132Z from Region 3625 (N13W78). There are currently 4 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with a slight chance for an M-class flare on days one, two, and three (02 Apr, 03 Apr, 04 Apr).
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 653 km/s at 01/0252Z. Total IMF reached 10 nT at 31/2121Z. The maximum southward component of Bz reached -7 nT at 01/0242Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 163 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on day one (02 Apr), quiet to active levels on day two (03 Apr) and quiet to minor storm levels on day three (04 Apr).
