SDF Number 39 Issued at 2200Z on 08 Feb 2021
IA. Analysis of Solar Active Regions and Activity from 07/2100Z to
08/2100Z: 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 (09 Feb, 10 Feb, 11 Feb).
IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 549 km/s at 07/2356Z. Total IMF reached 7 nT at
08/1947Z. The maximum southward component of Bz reached -7 nT at
08/1952Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 546 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (09 Feb) and quiet levels
on days two and three (10 Feb, 11 Feb).
