Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 330 Issued at 2200Z on 25 Nov 2008
IA. Analysis of Solar Active Regions and Activity from 24/2100Z
to 25/2100Z: Solar activity was very low. No flares were observed
during the past 24 hours. The visible disk remained spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field was predominantly unsettled. Solar wind
observations from the ACE spacecraft indicated the onset of a
recurrent coronal hole high-speed stream. Solar wind velocities
gradually increased from 285 km/s to 619 km/s during the period. The
interplanetary magnetic field (IMF) Bt reached a peak of 24 nT early
in the period. The IMF Bz ranged from +18 to -15 nT.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be predominantly unsettled with isolated active periods
possible on 26 November. Isolated periods of minor storm conditions
at high latitudes are also possible on 26 November. Quiet to
unsettled conditions are expected on 27 November. Conditions will
return to quiet on 28 November as the coronal hole high speed
subsides.
