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 008 Issued at 2200Z on 08 Jan 2005

IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z

Solar activity has been low. There has been a steady stream of B-class flares with a single C1.0 that occurred 08 Jan at 1957Z. Region 718 (S06E66) remains steady with a low probability for flare activity. Region 719 (S09E82) was newly numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low. Isolated C-class flare activity is possible from the regions near the southeast limb.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field has been at unsettled to severe storm levels. Disturbances in the geomagnetic field early on 08 Jan have been associated with solar wind transients and interplanetary magnetic field fluctuations.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to active levels. The solar wind transients should abate by the end of 08 Jan, and have little impact on the geomagnetic field for 09 through 11 Jan.
