Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 134 Issued at 2200Z on 14 May 2022

IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C4 event observed at 14/2016Z from Region 3010 (S15E48). There are currently 5 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with a chance for M-class flares and a slight chance for an X-class flare on days one, two, and three (15 May, 16 May, 17 May).
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 421 km/s at 14/2100Z. Total IMF reached 20 nT at 14/1844Z. The maximum southward component of Bz reached -6 nT at 13/2127Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 167 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on days one and three (15 May, 17 May) and unsettled to active levels on day two (16 May).
