Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 317 Issued at 2200Z on 12 Nov 2012
IA. Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
12/1022Z from Region 1610 (S22W10). There are currently 8 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be at low to
moderate levels on days one, two, and three (13 Nov, 14 Nov, 15 Nov).
IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: 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
12/0605Z. Total IMF reached 12 nT at 12/0724Z. The maximum southward
component of Bz reached -8.1 nT at 12/1934Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at mostly active with a chance for minor storm levels early on day
one (13 Nov) due to the arrival of the CMEs from 09/1524Z and 10/0539Z.
Activity is expected to decrease to generally unsettled levels on day 2
(14 Nov) as CME effects subside. On day 3 (15 Nov) conditions are
expected to return to mostly quiet levels.
