Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 26 Issued at 2200Z on 26 Jan 2020
IA. Analysis of Solar Active Regions and Activity from 25/2100Z to
26/2100Z: 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
with a slight chance for a C-class flare on days one, two, and three (27
Jan, 28 Jan, 29 Jan).
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 346 km/s at 25/2323Z. Total IMF reached 5 nT at
26/1524Z. The maximum southward component of Bz reached -4 nT at
26/1525Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 136 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (27 Jan, 28 Jan) and quiet to
unsettled levels on day three (29 Jan).
