Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 349 Issued at 2200Z on 15 Dec 2015
IA. Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 4 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (16 Dec,
17 Dec, 18 Dec).
IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 612 km/s at 15/0807Z. Total IMF reached 10 nT at 14/2104Z. The
maximum southward component of Bz reached -10 nT at 14/2104Z. Electrons
greater than 2 MeV at geosynchronous orbit reached a peak level of 122
pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (16 Dec) and quiet to
unsettled levels on days two and three (17 Dec, 18 Dec).
