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 activity was
at quiet to minor storm levels. An isolated period of minor storm
conditions occurred at 02/0600 - 0900 UTC. This was preceded with a
sudden impulse at the Boulder magnetometer of 45 nT at 02/0558 UTC.
This transient is presumed to be related to M3 x-ray flare that
occurred in old Region 9787 at 31/1444 UTC. The optical correlation
for this flare was attained using SOHO/EIT imagery, as this region
had rotated beyond the west limb.
