Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 356 Issued at 2200Z on 21 Dec 2016
IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: 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 (22
Dec, 23 Dec, 24 Dec).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic
field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 674 km/s at 21/1251Z. Total IMF
reached 15 nT at 21/1626Z. The maximum southward component of Bz reached
-11 nT at 21/0839Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 506 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at active to minor storm levels on day one (22 Dec) and quiet to
active levels on days two and three (23 Dec, 24 Dec).
