Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 70 Issued at 2200Z on 10 Mar 2020

IA.  Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: 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 (11 Mar, 12 Mar, 13 Mar).

IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 367 km/s at 10/0022Z. Total IMF reached 5 nT at
09/2101Z. The maximum southward component of Bz reached -3 nT at
10/0314Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 137 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (11 Mar) and quiet levels
on days two and three (12 Mar, 13 Mar).
