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
None.
C. Geomagnetic Activity Summary
The geomagnetic field ranged from
quiet to unsettled, before an isolated
minor storm occurred between
14/1500-14/1800, as the result of the onset of coronal hole, high
speed stream effects. Active conditions followed the minor storm
before returning to unsettled conditions by the end of the period.
