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 090 Issued at 0245Z on 31 Mar 2003 This report is compiled from data received at SWO on 30 MarA. Energetic Events

C. Geomagnetic Activity Summary
The geomagnetic field was
unsettled to active with isolated minor storm periods at high
latitudes. Solar wind signatures early this period indicate a
transition from transient flow to a high speed coronal hole stream.
Solar wind speed began the period near 400 km/s, but gradually
increased to near 650 km/s by end of period.

A LARGE WARM REGION OVER ASIA INTENSIFIES AND MOVES POLEWARDS WHILE
THE COLD REGION WEAKENS, INDICATING THE BEGINNING OF THE FINAL
WARMING.
