SDF Number 41 Issued at 2200Z on 10 Feb 2021
IA. Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: 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 (11 Feb, 12 Feb, 13 Feb).
IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 453 km/s at 10/0109Z. Total IMF reached 5 nT at
10/0042Z. The maximum southward component of Bz reached -3 nT at
10/1002Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 304 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (11 Feb, 12 Feb, 13
Feb).
