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
A proton enhancement at geosynchronous orbit was
observed by the GOES 13 spacecraft with a max flux of 3 PFUs at
26/0135Z. The enhancement appears to be correlated to the M4/1n
flare from Region 1387 (S22W42) on 25 December. This event did not
reach event threshold and has returned to background levels at the
time of this report.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet.
