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 2008

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

Solar activity was very low. No flares occurred during the last 24 hours. Region 980 (S08W23) decayed throughout the period.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was mostly quiet to unsettled during the past 24 hours. Solar wind speeds remain elevated but are slowly declining. 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 quiet to unsettled for the first day (09 January). Conditions should be predominantly quiet for the second and third days (10-11 January)
