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
The greater than 10 MeV proton flux at
geosynchronous orbit increased above 10 pfu at 14/0525 UTC, reached
a maximum of 3140 pfu at 15/0240 UTC, and decreased below 10 pfu at
15/1120 UTC.
C. Geomagnetic Activity Summary
The geomagnetic field was at
unsettled to severe storm levels. The arrival of a CME from 13 May
initiated the disturbance which caused severe storming conditions
between 15/0600 UTC and 0900 UTC. Solar wind speed at ACE increased
from approximately 200 km/s to 950 km/s. Solar wind speed has
declined to approximately 750 km/s by the end of the period.
