SDF Number 81 Issued at 2200Z on 21 Mar 2020
IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: 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 (22 Mar, 23 Mar, 24 Mar).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 525 km/s at 21/0957Z. Total IMF reached 7
nT at 21/0237Z. The maximum southward component of Bz reached -4 nT at

a peak level of 264 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (22 Mar, 23 Mar)
and quiet levels on day three (24 Mar).
