SDF Number 73 Issued at 2200Z on 13 Mar 2020
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 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 (14 Mar, 15 Mar, 16 Mar).
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 465 km/s at 13/2038Z. Total IMF reached 7
nT at 13/0247Z. The maximum southward component of Bz reached -6 nT at
