Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 26 Issued at 2200Z on 26 Jan 2018
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 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 (27 Jan, 28 Jan, 29 Jan).
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 521 km/s at 26/1325Z. Total IMF reached 8
nT at 26/0420Z. The maximum southward component of Bz reached -5 nT at
26/0235Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 169 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (27 Jan, 29
Jan) and quiet levels on day two (28 Jan).
