Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 16 Issued at 2200Z on 16 Jan 2013
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a long-duration C2 event
observed at 16/1923Z from a filament eruption near old Region 1650
(S31W79). There are currently 5 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for moderate levels on days one, two, and three (17 Jan, 18
Jan, 19 Jan).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: 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
467 km/s at 15/2142Z. Total IMF reached 6.4 nT at 16/2053Z. The maximum
southward component of Bz reached -4.0 nT at 16/1131Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 934 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to active levels for day 1 (17 Jan) and quiet to
unsettled levels for days 2 - 3 (Jan 18, Jan 19).
