Joint USAF/NOAA Report of Solar and Geophysical Activity


SDF Number 302 Issued at 2200Z on 29 Oct 2007


IA. Analysis of Solar Active Regions and Activity from 28/2100Z
to 29/2100Z: Solar activity was very low. The visible disk remained
spotless
IB. Solar Activity Forecast: Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field was quiet to unsettled. The greater than 2 MeV
electrons at geosynchronous orbit remained at high levels. The
coronal hole high speed stream appears to be waning.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled with a slight chance for an
isolated active period on day one (October 30). Days two and three
(October 31 - November 1) are expected to be quiet to unsettled.
