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 304 Issued at 2200Z on 30 Oct 2012IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z Solar activity was very low. Region 1598 (S11W51)
produced a B8 flare at 0137Z. A filament eruption occurred from
0640Z to 0855Z near S32E07 with a heliographic extent of 24 degrees.
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a chance for low level activity.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
Geomagnetic field activity was at quiet levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet on day 1 (31 October), increasing to a
chance for active levels with the arrival of the 27 and 28 October
CMEs late in the day. Unsettled to active with a chance for minor
storm levels are expected on day 2 (1 November) from CME effects.
On day 3 (2 November) conditions are expected to decline to quiet to
unsettled with a chance for active as CME effects subside.
