Her (slightly edited) report: Today's Radio Science egress campaign ended a few hours ago. Due to limited DSN coverage, eight egress measurements were planned. All measurements were successfully acquired as follows: Occult# DOY DSS Beg/End Rec Begin Record (UTC) (PDT) ------- --- ----- ----------- ------------------ 19397e 192 25 1002/1012 Fri 7/11 03:02 a.m. 19398e 192 25/43 1159/1209 Fri 7/11 04:59 a.m. 19399e 192 25/43 1357/1407 Fri 7/11 06:57 a.m. 19400e 192 43 1555/1605 Fri 7/11 08:55 a.m. 19401e 192 43 1752/1802 Fri 7/11 10:52 a.m. 19402e 192 43 1950/2000 Fri 7/11 12:50 p.m. 19403e 192 43 2148/2158 Fri 7/11 02:48 p.m. 19404e 192 65 2345/2355 Fri 7/11 04:45 p.m. With help from Elias Barbinis (Radio Science Systems Group), all measurements were monitored in real-time. Broadened spectral energy reminiscent of surface echoes were observed in the open-loop displays during all measurements.

The data collected from occultation 19902i (DSS 43, start time 2003/192- 21:03:00) have +/-0.3 dB fluctuations in the carrier level. Some of the egress measurements mentioned by Aseel (under Miscellaneous) are listed above. Because of some unexpected query problems, the remainder have been delayed and will be reported tomorrow. Quick-look processing shows very strong surface echoes on ingress occultations, but very weak reflections during egress. This would be consistent with a slight mispointing of the high gain antenna, with the bias toward the planet on ingress.
