Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 72 Issued at 2200Z on 13 Mar 2021
IA. Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: Solar activity has been at very low levels for the past 24
hours. There is currently 1 numbered sunspot region on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (14 Mar, 15 Mar, 16 Mar).
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 576 km/s at 13/2046Z. Total IMF reached 15
nT at 13/0257Z. The maximum southward component of Bz reached -11 nT at
13/0304Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 226 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (14 Mar) and quiet levels
on days two and three (15 Mar, 16 Mar).
