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 310 Issued at 2200Z on 05 Nov 2012

IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z

Solar activity was low. The largest event was a C2 flare at 05/1839Z from an unnumbered region around the southeast limb. New Regions 1607 (N12W47) and 1608 (S20E62) were numbered and both appear to be unipolar spot groups. The remaining spot groups were quiet and stable. No Earth-directed CMEs (coronal mass ejections) were observed during the reporting period.
IB. Solar Activity Forecast
Solar activity is expected to be very low with a chance for C-flare activity.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
Geomagnetic field activity was at quiet levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be mostly quiet for the next three days (06-08 November).
