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 306 Issued at 2200Z on 02 Nov 2005IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity was at very low levels today. Region
818 (S08E06) produced a B2 x-ray flare and showed decay in sunspot
area. Region 819 (S09W01) remains a simple beta magnetic
configuration. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low levels.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field was at quiet to unsettled levels. A solar
sector boundary crossing passed the ACE spacecraft at approximately
02/1800Z. The solar wind speed increased from near 400 km/sec to
over 550 km/sec shortly thereafter.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels. Active to isolated
minor storm conditions may become possible late on 04 Nov and
through 05 Nov due to a recurrent coronal hole.
