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 greater than 100 MeV proton event commenced at 13/0300 UTC, reached maximum at 13/0525 UTC with 88.7 pfu and ended at 14/1150 UTC. The greater than 10 MeV event that started 13/0310 UTC is still in progress with current levels increasing due to enhancement from an X1.5 flare from Region 930 (S05W47). Another greater than 100 MeV proton event commenced at 14/2255 UTC .
C. Geomagnetic Activity Summary
The geomagnetic field reached major to severe storm levels. The ACE satellite observed the shock from the 13 December CME at 14/1356 UTC. A sudden impulse was observed at the Boulder magnetometer at 14/1416 UTC with a deviation of 26 nT. Periods of major to severe storming occurred between 14/1200 UTC and 14/1800 UTC. Solar wind speed is currently 900 km/s.
