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 303 Issued at 2200Z on 30 Oct 2007IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z Solar activity was very low. The visible solar disk
remains spotless.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field began the day with a brief episode of minor
storming but quickly subsided to quiet to unsettled conditions as
the influence of the coronal hole high speed stream diminished. The
greater than 2 MeV electron flux reached high levels again today.
IIB. Geophysical Activity Forecast
The geomagnetic field
conditions are expected to range from quiet to unsettled on day one
(October 31), becoming predominantly quiet for the remainder of the
period (November 1-2).
