Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 28 Issued at 2200Z on 28 Jan 2020
IA. Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: 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 (29 Jan, 30 Jan, 31 Jan).
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 373 km/s at 28/1947Z. Total IMF reached 8 nT at
28/1947Z. The maximum southward component of Bz reached -6 nT at
28/1936Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 151 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (29 Jan, 30 Jan)
and quiet levels on day three (31 Jan).
