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 307 Issued at 2200Z on 03 Nov 2009IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity was very low. The SOHO/LASCO imagery
observed a slow coronal mass ejection (CME) off the southwest limb
at 0501 UTC on 31 October. The CME appears to be earth directed
with a plane-of sky speed of 380 km/s.
IB. Solar Activity Forecast
Solar activity is expected to be low.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
Geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet on day 1 (4 November). Unsettled conditions
are expected on day 2 (5 November) due to possible effects from the
CME observed on 31 October. Quiet levels are expected to return on
day 3 (6 November).
