SDF Number 34 Issued at 2200Z on 03 Feb 2020
IA. Analysis of Solar Active Regions and Activity from 02/2100Z to
03/2100Z: 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 (04 Feb, 05 Feb, 06 Feb).
IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 417 km/s at 03/1547Z. Total IMF reached 5 nT at
03/0151Z. The maximum southward component of Bz reached -4 nT at
02/2135Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 315 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (04 Feb, 05 Feb) and quiet to
active levels on day three (06 Feb).
