Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 307 Issued at 2200Z on 02 Nov 2012
IA. Analysis of Solar Active Regions and Activity from 01/2100Z
to 02/2100Z: Solar activity was very low. Today's activity consisted
of a few, low-level B-class flares. All the regions on the disk were
quiet and stable.
IB. Solar Activity Forecast: Solar activity is expected to be very
low for the next three days with just a chance for an isolated
C-class event.
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z:
The geomagnetic field was mostly quiet during the past 24 hours. The
interplanetary magnetic field (IMF) steadily weakened throughout the
period from initial values around 10 nT to day-end values around 3
nT. The z-component of the IMF (Bz) turned northwards at about 0300Z
and solar wind velocity was at nominal values between 300 to 320
km/s.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be predominantly quiet for the next three days (03-05
Nov).
