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 186 Issued at 2200Z on 05 Jul 2009

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

Solar activity increased to low levels. Region 1024 (S27W13) produced a C2/Sf flare at 05/0713Z, as well as frequent B-class flares. Minor changes were observed in the region since its rapid emergence yesterday. It retained a beta magnetic structure with some polarity mixing evident in its intermediate spots.
IB. Solar Activity Forecast
Solar activity is expected to be very low. There is also a chance for an isolated C-class flare from Region 1024.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
Geomagnetic field activity was at quiet levels.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is expected to be at quiet levels throughout the forecast period (06 - 08 July).
