Today's report also includes data from this month's egress campaign; a total of eight egress measurements were collected on DOY 021 by DSS 63, 25, and 45. Aseel Anabtawi comments: The January Radio Science egress campaign ended a few hours ago. Only eight egress measurements were planned due to limited DSN coverage. All measurements were monitored in real-time and were successfully acquired as follows: DOY DSS Beg/End Rec Begin Record (UTC) (PST) --- --- ----------- ------------ 021 63 1038/1048 02:38 a.m. 021 25 1236/1246 04:36 a.m. 021 25 1433/1443 06:33 a.m. 021 25 1631/1641 08:31 a.m. 021 25 1828/1838 10:28 a.m. 021 45 2026/2036 12:25 p.m. 021 45 2224/2234 02:24 p.m. 022 45 0022/0032 04:22 p.m. Four out of the eight collected egress measurements had a -2 dB rolloff in the free-space carrier amplitude over 1 minute immediately after egress, as noted in the table below. The cause is currently unknown; motion of the spacecraft antenna is a possible explanation. The SOE provides no clues. The rolloff may not reduce the occultation science return from these measurements significantly if the phase is not also affected. Note that the rolloff occurrs for every second egress measurement and is independent of which ground antenna was used.
