Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 21 Issued at 2200Z on 21 Jan 2017
IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C9 event observed at
21/0726Z from Region 2628 (N12E36). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
chance for M-class flares on days one, two, and three (22 Jan, 23 Jan,
24 Jan).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 536 km/s at 20/2126Z. Total IMF reached 6
nT at 21/1541Z. The maximum southward component of Bz reached -4 nT at
21/0512Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 2839 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (22 Jan) and quiet levels
on days two and three (23 Jan, 24 Jan).
