Geophysical 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 Solar and Geophysical Activity Summary
SGAS Number 106 Issued at 0245Z on 16 Apr 2003 This report is compiled from data received at SWO on 15 AprA. Energetic Events

C. Geomagnetic Activity Summary
The geomagnetic field was at
unsettled to minor storm levels. Solar wind velocity was elevated
near 575 km/s and a prolonged period of southward Bz produced active
conditions for most of the day with one period of isolated minor
storm levels. By the end of the day Bz shifted northward and
activity has subsided to unsettled levels. Greater than 2 MeV
electron flux reached high levels.
