Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 53 Issued at 2200Z on 22 Feb 2013
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
22/1222Z from Region 1678 (N10W80). There are currently 6 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 day one (23 Feb) and expected to
be very low with a chance for a C-class flares on days two and three (24
Feb, 25 Feb).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: 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
433 km/s at 22/0435Z. Total IMF reached 6 nT at 21/2321Z. The maximum
southward component of Bz reached -6 nT at 21/2138Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (23 Feb, 24 Feb)
and quiet levels on day three (25 Feb).
