Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 354 Issued at 2200Z on 19 Dec 2016
IA. Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: 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 (20
Dec, 21 Dec, 22 Dec).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 394 km/s at 19/0645Z. Total IMF reached 6 nT at
19/1941Z. The maximum southward component of Bz reached -5 nT at
19/1104Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 528 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (20 Dec), unsettled to minor
storm levels on day two (21 Dec) and active to minor storm levels on day
three (22 Dec).
