Geophysical report

Viewing archive of Tuesday, 1 March 2005

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.

C. Geomagnetic Activity Summary

The geomagnetic field was quiet to unsettled with isolated active conditions late in the period. A coronal hole high speed stream is in effect; however, the IMF Bz was predominantly northward. Solar wind speed ranged from 550 - 600 km/s.
