SDF Number 40 Issued at 2200Z on 09 Feb 2021
IA. Analysis of Solar Active Regions and Activity from 08/2100Z to
09/2100Z: 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 (10 Feb, 11 Feb, 12 Feb).
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 518 km/s at 09/0904Z. Total IMF reached 6
nT at 09/0348Z. The maximum southward component of Bz reached -5 nT at
09/0013Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 268 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (10 Feb, 11 Feb, 12
Feb).
