Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 14 Issued at 2200Z on 14 Jan 2013
IA. Analysis of Solar Active Regions and Activity from 13/2100Z to
14/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C6 event observed at
14/0122Z from Region 1652 (N18W64). There are currently 6 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low
levels with moderate levels likely on days one, two, and three (15 Jan,
16 Jan, 17 Jan).
IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: 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
593 km/s at 14/0352Z. Total IMF reached 8.6 nT at 13/2316Z. The maximum
southward component of Bz reached -6.8 nT at 14/0015Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 109 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for days one and two (15-16 Jan) and unsettled
levels on day three (17 Jan).
