Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 358 Issued at 2200Z on 24 Dec 2015
IA. Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
24/0212Z from Region 2473 (S22E35). There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one and two (25 Dec, 26 Dec) and expected to be low with a chance
for M-class flares on day three (27 Dec).
IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
573 km/s at 24/2041Z. Total IMF reached 10 nT at 24/0434Z. The maximum
southward component of Bz reached -7 nT at 24/0418Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 4505 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (25 Dec) and quiet to
unsettled levels on days two and three (26 Dec, 27 Dec).
