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 was at quiet
to unsettled levels. Solar wind speed has continued to gradually
decrease, ending the period near 525 km/s. The greater than 2 MeV
electron flux at geo-synchronous orbit reached high levels.
D. Stratwarm
None

F. Comments
Daily X-Ray Background Flux value is estimated from plotted data, pending repair of the automated algorithm. Repair is in progress. SSN is estimated based on SRS data.
