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 061 Issued at 2200Z on 02 Mar 2005

IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z

Solar activity continues at very low levels. Newly numbered Region 740(S07W24) emerged today and quickly developed into a CSO Beta spot group.
IB. Solar Activity Forecast
Solar activity is expected to continue at very low levels.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field was mostly unsettled, becoming quiet late in the UTC day. A high speed coronal hole stream remains geoeffective. Solar wind speed ranged from 600 - 700 km/s; however, a downward trend was observed through the day. The IMF Bz varied between +/- 4 nT. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to continue at quiet to unsettled levels. Quiet levels are expected on 04 and 05 March as the high speed solar wind stream rotates out of a geoeffective position.
