Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 324 Issued at 2200Z on 19 Nov 2012

IA.  Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
19/0228Z from Region 1618 (N09E28). Region 1618 has a beta-gamma
magnetic configuration. There are currently 7 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 (20 Nov, 21 Nov, 22 Nov).

IIA.  Geophysical Activity Summary 18/2100Z to 19/2100Z: 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 433 km/s at
19/0114Z. Total IMF reached 6.2 nT at 19/2058Z. The maximum southward
component of Bz reached -4.9 nT at 19/0848Z. Electrons greater than 2
MeV at geosynchronous orbit reached a peak level of 1465 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for the next three days (20 Nov, 21 Nov, 22 Nov).
