Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 23 Issued at 2200Z on 23 Jan 2013
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 4 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 (24 Jan, 25 Jan, 26 Jan).
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: 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 311 km/s at
23/0055Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 367 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (24Jan). Quiet to unsettled levels are
expected for days two and three (24 Jan, 25 Jan) due to the anticipated
onset of a coronal hole high speed stream.
