Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 30 Issued at 2200Z on 30 Jan 2020
IA. Analysis of Solar Active Regions and Activity from 29/2100Z to
30/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (31 Jan, 01 Feb, 02 Feb).
IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 501 km/s at 30/1810Z. Total IMF reached 8
nT at 30/1625Z. The maximum southward component of Bz reached -7 nT at
30/1624Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 141 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (31 Jan, 01 Feb, 02
Feb).
