Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 22 Issued at 2200Z on 22 Jan 2013
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: 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 expected to be at low
levels 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 levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 362 km/s at
21/2124Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 288 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels for the next three days (23 Jan, 24
Jan, 25 Jan).
