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.

C. Geomagnetic Activity Summary
The geomagnetic field was at
unsettled to severe storm levels. Major storm periods at middle
latitudes with severe storm periods at higher latitudes were
observed between 05/0000 UTC and 05/0600 UTC. At approximately 0200
UTC on 05 April, solar wind speed at ACE increased from 560 km/s to
650 km/s while temperature, density, and the IMF decreased. In
addition, Bz remained southward for several hours following this
sudden change.
