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 066 Issued at 2200Z on 07 Mar 2005

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

Solar activity was very low. New Region 742 (S05E67) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was mostly active with minor and major storm periods. Heightened activity was due to the presence of a geoeffective high speed stream that began early on 06 March. Solar wind speed at ACE remained elevated between 600 km/s and 700 km/s. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be unsettled to active with a possibility for periods of minor storm levels on 08 March. On 09 March, conditions are expected to be unsettled to active. On 10 March, conditions are expected to be mostly unsettled.
