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 311 Issued at 2200Z on 07 Nov 2006

IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z

Solar activity was low. An active region rotating around the east limb produced three C-class flares during the past 24 hours. The largest of these was a C6 flare at 07/1346Z. Bright X-ray emission is seen above the east limb in GOES-13 SXI imagery, and a very active loop structure is seen in EIT imagery. Sunspots are just now rotating onto the visible disk. Two fast CMEs have originated from this region during the past two days (both were in the range of 1500-2000 km/s in SOHO LASCO imagery). ACE SIS data shows a slight enhancement in the greater than 10 MeV and 30 MeV protons beginning soon after the CME that was observed in LASCO imagery at 06/1842Z.
IB. Solar Activity Forecast
Solar activity is expected to be low. There is a slight chance for an isolated M-class flare from the region rotating onto the east limb.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet on 08 November. Unsettled to active conditions, with possible minor storm periods, are expected on 09-10 November. The increase is expected due to a recurrent coronal hole rotating into a geoeffective position.
