Presentation Transcript

  1. Low Energy Electron Observations (LEE, AESOP and the Historical Context) Paul Evenson and John Clem University of Delaware Department of Physics and Astronomy Bartol Research Institute

  2. For Decades LEE has been the Cosmic Ray Electron “Standard Candle” Magnetic Polarity • Time profile of helium and electron observations at a rigidity of 1.2 GV • Alternation with solar magnetic polarity is probably due to “drifting” across magnetic field lines • Large symbols are LEE flights, others are spacecraft “calibrated” by LEE • LEE 2009 is now beeing prepared in Kiruna • We hope PAMELA is next

  3. Present Status of Positron Observations and Theory • New “drift model” modulation calculation with a flat current sheet for two diffusion coefficients can reproduce AMS or PAMELA but not both
