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 unsettled to minor storm periods with isolated major storm levels at high latitudes. A gradual rise in the solar wind speed began early in the period, rising to a peak speed near 700 km/s, before gradually declining to near 550 km/s. The IMF Bz was predominantly southward during the first half of the period, which accounted for the most disturbed conditions. A greater than 10 MeV proton enhancement began soon after today's long duration M8 flare.
D. Stratwarm
