Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 71 Issued at 2200Z on 11 Mar 2020

IA.  Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: 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 (12 Mar, 13 Mar, 14 Mar).

IIA.  Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 324 km/s at 11/1533Z.  Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 175 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (12 Mar, 13 Mar, 14
Mar).
