Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 211 Issued at 2200Z on 30 Jul 2022

IA.  Analysis of Solar Active Regions and Activity from 29/2100Z to
30/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 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 on days one, two, and three (31 Jul,
01 Aug, 02 Aug).

IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 373 km/s at 30/1804Z. Total IMF reached 10 nT at
30/1857Z. The maximum southward component of Bz reached -6 nT at
30/1127Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1067 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (31 Jul) and quiet levels on
days two and three (01 Aug, 02 Aug).
