Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 44 Issued at 2200Z on 13 Feb 2013
IA. Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be at very
low levels with a chance for a C-class flare on days one, two, and three
(14 Feb, 15 Feb, 16 Feb).
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: 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
418 km/s at 13/0352Z. Total IMF reached 11.3 nT at 13/1650Z. The maximum
southward component of Bz reached -9.3 nT at 13/1831Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for the next three days (14 Feb, 15 Feb, 16 Feb).
