Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 54 Issued at 2200Z on 23 Feb 2013
IA. Analysis of Solar Active Regions and Activity from 22/2100Z to
23/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
23/1609Z from Region 1678 (N08W93). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (24 Feb,
25 Feb, 26 Feb).
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: 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
432 km/s at 23/1450Z. Total IMF reached 6 nT at 23/1449Z. The maximum
southward component of Bz reached -6 nT at 23/1449Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (24 Feb) and quiet levels
on days two and three (25 Feb, 26 Feb).
