Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 212 Issued at 2200Z on 30 Jul 2020

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
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 382 km/s at 29/2217Z. Total IMF reached 7 nT at
30/0405Z. The maximum southward component of Bz reached -7 nT at
30/0405Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 230 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (31 Jul) and quiet to unsettled levels
on days two and three (01 Aug, 02 Aug).
