Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 25 Issued at 2200Z on 25 Jan 2020
IA. Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: 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 (26 Jan, 27 Jan, 28 Jan).
IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 332 km/s at 25/0407Z. Total IMF reached 6 nT at
25/0423Z. The maximum southward component of Bz reached -4 nT at
25/0308Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 176 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (26 Jan, 27 Jan, 28
Jan).
