Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 52 Issued at 2200Z on 21 Feb 2016
IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 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 (22 Feb,
23 Feb, 24 Feb).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 755 km/s at
21/0712Z. Total IMF reached 6 nT at 21/1932Z. The maximum southward
component of Bz reached -4 nT at 21/0321Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 21836 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (22 Feb, 23 Feb) and quiet to
unsettled levels on day three (24 Feb).
