Energetic Proton Maps for the South Atlantic Anomaly

A new set of flux intensity maps for energetic protons in the South Atlantic Anomaly (SAA) region is presented for the epoch 2000-2006 based on data from the Compact Environmental Anomaly Sensor (CEASE) flown onboard the Tri-Service Experiment-S (TSX-5) satellite in a 410 km x 1710 km, 69 degree inc...

Description
Summary:A new set of flux intensity maps for energetic protons in the South Atlantic Anomaly (SAA) region is presented for the epoch 2000-2006 based on data from the Compact Environmental Anomaly Sensor (CEASE) flown onboard the Tri-Service Experiment-S (TSX-5) satellite in a 410 km x 1710 km, 69 degree inclination orbit. Maps for >23 MeV, >38 MeV, >66 MeV , and >94 MeV protons have ben constructed and boundary contours for 1/2 maximum, 1/10 maximum, and 3 times the background standard deviation derived. Estimates are given of the integral energy spectra as a function of altitude from 400 km to 1650 km, an interval spanning the range where the controlling factor in the dynamics changes from the neutral density to the global magnetic field. The position of the maximum flux point is compared to that determined from earlier measurements in the 1994-1996 epoch and found to be consistent with the well-known westward drift.
