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 2009IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z
Solar activity was very low. Region 1029 (N16W84)
produced two B-class flares during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
Geomagnetic field activity was at quiet to active levels. This
increase in activity was most likely the result of a sector boundary
crossing.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be mostly quiet for the next three days (31 October - 02
November).
