Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 80 Issued at 2200Z on 20 Mar 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 Mar, 22 Mar, 23 Mar).

IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 498 km/s at 19/2255Z. Total IMF reached 5
nT at 20/1706Z. The maximum southward component of Bz reached -4 nT at
20/2038Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 421 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (21 Mar) and quiet levels
on days two and three (22 Mar, 23 Mar).
