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
unsettled to severe storm levels (estimated Kp of 7). A strong
shock was observed at the Ace spacecraft at 05/0241Z, and was
followed by transient flow with enhanced density, speed, and
magnetic fields. Major to severe storming at all latitudes began
after 0300Z. There were two intervals of strongly negative Bz: the
first was from 05/0504 - 0543Z with Bz values reaching -27 nT, and
the second was from 05/0958 - 1119Z with Bz values reaching -23 nT.
Severe levels were seen at high latitudes from 05/0300 - 1500Z, and
mid-latitudes also attained the K=7 level from 05/0600 - 0900Z. The
disturbance appeared to be subsiding during the last hours of the
day to unsettled to active levels.
