Hello,

This gravity pass at DSS 15 went well. The station was having some
problems just after the switch to the LGA, so they did not lock up as
quickly as usual.

Times of interest (all UTC ERT):

160-20:28:43  switch to LGA
160-20:39:20  ISH - begin slew to NADIR
160-20:50:48  receivers in lock on LGA signal
160-21:11:20  Periapsis 355
160-21:23:22  ISH - begin rollout
160-21:25:30  receiver out of lock before this time
160-21:43:22  ANS
160-21:55:13  switch back to HGA

The next gravity pass is Periapsis 357 (approximately 161-20:29:24 UTC
ERT).
