Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 302 Issued at 2200Z on 29 Oct 2007IA. 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 30 - November 1) are expected to be quiet to unsettled.
