Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 211 Issued at 2200Z on 29 Jul 2020

IA.  Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: 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 (30 Jul, 31 Jul, 01 Aug).

IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 378 km/s at 28/2102Z. Total IMF reached 6 nT at
29/1941Z. The maximum southward component of Bz reached -3 nT at
29/0505Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 268 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (30 Jul, 31 Jul, 01
Aug).
