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 minor storm levels. This activity is most likely related to
the passage of one of the CMEs observed over the northwest limb
earlier this week.
D. Stratwarm
None
