These start with occultation 12437i (DSS 54, 2001/353-12:56:00) and repeat every 117 min until occultation 12450i (DSS 65, 2001/354-14:26:00). The following observations were captured using two antennnas: Occultation Start Date/Time DSS-1 DSS-2 ----------- ----------------- ----- ----- 12446e 2001/354-05:06:00 15 34 12449i 2001/354-12:29:00 34 65 Egress occultation 12438e (DSS 54, 2001/353-13:24:00) appears to have been lost. A signal is present in the recording only for approximately the last minute, well after egress and after telemetry had been turned on. Cause for this anomaly is not know.

Minimum angle (1.15 deg) occurs on 11 August 2002. Figure provided by Pat Esposito of the MGS Navigation Team. Figure ====== Plot(s) illustrate some of the points made in the text. Each plot is a PostScript file, created and printable on our SOPC. For report text file HEAydddC.TXT Figure N will be labeled HEAydddC.PSN and sent as the N+1st e-mail message of a set. We assume that you can strip off the e-mail headers and either display or print copies of the figures on a machine in your area.
