Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 22 Issued at 2200Z on 22 Jan 2014
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
22/1905Z from Region 1955 (S14W18). There are currently 10 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (23 Jan, 24 Jan,
25 Jan).
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
629 km/s at 22/0744Z. Total IMF reached 11 nT at 21/2121Z. The maximum
southward component of Bz reached -6 nT at 22/2009Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (23 Jan) and quiet levels
on days two and three (24 Jan, 25 Jan).
