Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 42 Issued at 2200Z on 11 Feb 2016
IA. Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
11/1649Z from Region 2497 (N13W06). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (12
Feb, 13 Feb, 14 Feb).
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
407 km/s at 10/2130Z. Total IMF reached 11 nT at 11/2057Z. The maximum
southward component of Bz reached -10 nT at 11/2052Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 104 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (12 Feb), quiet to unsettled
levels on day two (13 Feb) and quiet levels on day three (14 Feb).
Protons have a slight chance of crossing threshold on day one (12 Feb)
and have a slight chance of crossing threshold on days two and three (13
Feb, 14 Feb).
