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 038 Issued at 2200Z on 07 Feb 2008

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

Solar activity was very low. No flares occurred. The visible disk remained spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled during days 1 - 2 (08 - 09 Feb). Activity is expected to increase to unsettled to active levels on day 3 (10 Feb) due to a recurrent coronal hole high-speed stream.
