SDF Number 202 Issued at 2200Z on 20 Jul 2020

IA.  Analysis of Solar Active Regions and Activity from 19/2100Z to
20/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (21 Jul, 22 Jul, 23 Jul).

IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 366 km/s at 20/0935Z.  Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 267 pfu.
