Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 191 Issued at 2200Z on 10 Jul 2021

IA.  Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: 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
on days one, two, and three (11 Jul, 12 Jul, 13 Jul).

IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 447 km/s at 10/1727Z. Total IMF reached 11
nT at 10/0301Z. The maximum southward component of Bz reached -9 nT at
10/0254Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 161 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (11 Jul) and quiet to
active levels on days two and three (12 Jul, 13 Jul).
