Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 175 Issued at 2200Z on 23 Jun 2020

IA.  Analysis of Solar Active Regions and Activity from 22/2100Z to
23/2100Z: 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 (24 Jun, 25 Jun, 26 Jun).

IIA.  Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 308 km/s at 23/1304Z. Total IMF reached 5 nT at
23/2015Z. The maximum southward component of Bz reached -5 nT at
23/2002Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 150 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (24 Jun, 25 Jun, 26
Jun).
