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 RANGED FROM
QUIET TO SEVERE STORM LEVELS. MAJOR TO SEVERE STORM CONDITIONS
DECREASED EARLY ON 16 JULY. THE GREATER THAN 100 MEV PROTON EVENT
THAT BEGAN 14/1040Z, PEAKED AT 410 PFU AT 14/1620Z, AND ENDED AT
16/0400Z. THE GREATER THAN 10 MEV PROTON EVENT CONTINUES TO DECLINE
FROM A PEAK OF 24000 PFU'S AT 15/1230Z AND IS CURRENTLY AROUND 180
PFU'S. THE PCA ASSOCIATED WITH THE X5/3B ON 14 JULY PEAKED AT
15/1436Z WITH 49.0 DB AND IS STILL IN PROGRESS. A MODERATE FORBUSH
DECREASE CONTINUED THROUGHOUT THE PERIOD.
