Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 64 Issued at 2200Z on 04 Mar 2020

IA.  Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: 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 (05 Mar, 06 Mar, 07 Mar).

IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 425 km/s at 03/2254Z. Total IMF reached 6
nT at 04/1714Z. The maximum southward component of Bz reached -5 nT at
04/1613Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 388 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (05 Mar) and quiet levels
on days two and three (06 Mar, 07 Mar).
