Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 74 Issued at 2200Z on 15 Mar 2022

IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z

Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M1 event observed at 15/1239Z from Region 2965 (N24W17). There are currently 4 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (16 Mar, 17 Mar, 18 Mar).
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 446 km/s at 15/0640Z. Total IMF reached 13 nT at 14/2109Z. The maximum southward component of Bz reached -5 nT at 15/1522Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 234 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on day one (16 Mar) and quiet to unsettled levels on days two and three (17 Mar, 18 Mar).
