Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 23 Issued at 2200Z on 23 Jan 2014
IA. Analysis of Solar Active Regions and Activity from 22/2100Z to
23/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 9 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (24
Jan, 25 Jan, 26 Jan).
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
525 km/s at 22/2108Z. Total IMF reached 8 nT at 23/0042Z. The maximum
southward component of Bz reached -5 nT at 23/0258Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (24 Jan, 25 Jan, 26
Jan).
