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 007 Issued at 2200Z on 07 Jan 2008

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

Solar activity was low. Region 980 (S06W03) produced a C1 x-ray flare today at 1527Z. The group appears to be re-emerging but is still small and simple. An eruptive event was observed near plage Region 981 (N27W17) at about 0230Z and was associated with a B1 x-ray event as well as a small CME observed by the COR2 coronagraph on the STEREO-B spacecraft.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low for the next three days (08-10 January).
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was predominantly unsettled to active during the past 24 hours. Solar wind speed remained elevated throughout the day due to the continuing influence of a high speed stream. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be mostly unsettled with a chance for isolated active periods for the first day (08 January). Conditions are expected to decline to quiet to unsettled for the second day (09 January) and are expected to be quiet for the third day (10 January).
