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.
Report of Solar-Geophysical Activity 2005 Mar 04 2250 UTC# Prepared jointly by the U.S. Dept. of Commerce, NOAA, #Space Environment Center and the U.S. Air Force. #
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 063 Issued at 2200Z on 04 Mar 2005IA. Analysis of Solar Active Regions and Activity from 03-2100Z to 04-2100Z
Solar activity was at very low levels. Region 741
(N12E70) is a newly numbered CSO beta group.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low levels.
IIA. Geophysical Activity Summary 03-2100Z to 04-2100Z
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet levels on 5 March. Isolated active
conditions may occur late on 6 March due to the onset of a recurrent
high speed coronal hole stream. Isolated minor storm conditions are
possible on 7 March due to the continued effects from the high speed
stream.
