Geophysical report

Viewing archive of Tuesday, 22 October 2002

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.

B. Proton Events

None

C. Geomagnetic Activity Summary

The geomagnetic field was at quiet to unsettled levels. Solar wind speed has continued to gradually decrease, ending the period near 525 km/s. The greater than 2 MeV electron flux at geo-synchronous orbit reached high levels.

D. Stratwarm

None
