Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 216 Issued at 2200Z on 04 Aug 2022

IA.  Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one, two, and three (05 Aug, 06 Aug, 07 Aug).

IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 518 km/s at 03/2153Z. Total IMF reached 6 nT at
04/0430Z. The maximum southward component of Bz reached -4 nT at
04/1607Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 297 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (05 Aug) and quiet to unsettled levels
on days two and three (06 Aug, 07 Aug).
