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 067 Issued at 2200Z on 08 Mar 2005

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

Solar activity was very low. The largest event of the period was a B5.4 flare that occurred at 08/0309Z from Region 742 (S06E56). No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was at unsettled to minor storm levels. Solar wind speed at ACE increased to a maximum near 820 km/s at about 08/0810Z and declined to 700 km/s by the end of the reporting period. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels again today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be unsettled to active with minor storm periods possible at high latitudes on 09 March. On 10 March, conditions are expected to be mostly unsettled as the coronal hole high speed stream rotates out of a geoeffective position. On 11 March, conditions are expected to be quiet to unsettled.
