Hello,

Periapsis 384 occurred at DSS 15.

Times of interest (all UTC ERT):

174-22:10:38  switch to LGA
174-22:15:26  receivers in lock on LGA signal
174-22:21:15  ISH - begin slew to NADIR
174-22:53:15  Periapsis 384
174-23:05:17  ISH - begin rollout
174-23:09:26  receiver out of lock before this time
174-23:25:17  ANS
174-23:37:08  switch back to HGA

The next gravity pass is Periapsis 385 (approximately 175-10:31 UTC ERT).
