Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 86 Issued at 2200Z on 26 Mar 2020

IA.  Analysis of Solar Active Regions and Activity from 25/2100Z to
26/2100Z: 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 (27 Mar, 28 Mar, 29 Mar).

IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 423 km/s at 26/0433Z. Total IMF reached 5 nT at
26/1658Z. The maximum southward component of Bz reached -3 nT at
26/2058Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1658 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (27 Mar, 28 Mar, 29
Mar).
