Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 82 Issued at 2200Z on 22 Mar 2020
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: 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 (23 Mar, 24 Mar, 25 Mar).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 493 km/s at 22/0931Z. Total IMF reached 6
nT at 22/0012Z. The maximum southward component of Bz reached -4 nT at
22/0127Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 547 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (23 Mar) and quiet levels
on days two and three (24 Mar, 25 Mar).
