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.

Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 257 Issued at 0245Z on 14 Sep 2005 This report is compiled from data received at SWO on 13 SepA. Energetic Events

B. Proton Events
The greater than 10 MeV proton event that began
on 08 September fell below the 10 pfu threshold today; however, a
new influx of protons has raised levels to around 7 pfu's by the end
of the reporting period and is expected to continue rising.
C. Geomagnetic Activity Summary
The geomagnetic field has been at
unsettled to major storm levels. Storm conditions persisted through
much of this period due to transient flow from the intense CME
activity over the past several days. Conditions returned to
predominantly unsettled levels by the end of the period. Solar wind
speed at ACE remains elevated, but decreased from a high near 770
km/s to approximately 650 km/s by the end of the period.
