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.
