APPENDIX_C.TXT PURPOSE: Describe the SNOE orbit with respect to the southern auroral region The SNOE spacecraft samples the southern auroral region during orbits 0 through 5 and 12 through 14 (inclusive). SNOE does not fly through the southern auroral region on orbits 6 through 11. This is due to the fact that the orbit does not take the spacecraft poleward of -82.5 degrees.
