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.

B. Proton Events
Greater than 10 MeV protons are slightly elevated
above background.
C. Geomagnetic Activity Summary
Geomagnetic activity was at quiet
to unsettled levels. Shock arrival from the two CMEs (M6/2N on
22/1502 UTC and X1/2B on 22/1759 UTC) occurred at 25/0850 UTC with a
sudden impulse of 22 nT recorded on the Boulder magnetometer. A
north directed Bz component to the interplanetary magnetic field
resulted in only unsettled conditions.
