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.

None
C. Geomagnetic Activity Summary
The geomagnetic field ranged from
active to severe storm conditions. An extended period of sustained
southward Bz followed the shock observed at ACE early on 19 Mar. The
geomagnetic storm was still in progress through the end of the
period, but was showing signs of weakening. This disturbance is
believed to be associated with the CME observed early on 16 Mar.
