Hello,

Periapsis 385 occurred at DSS 65.

Times of interest (all UTC ERT):

175-09:48:32  switch to LGA
175-09:53:00  receivers in lock on LGA signal (approximate)
175-09:59:09  ISH - begin slew to NADIR
175-10:31:09  Periapsis 385
175-10:43:11  ISH - begin rollout
175-10:46:48  receiver out of lock before this time
175-11:03:11  ANS
175-11:08:30  receivers in lock again (approximate)
175-11:15:02  receivers out of lock before this time
175-11:15:02  switch back to HGA

The next gravity pass is Periapsis 387 (approximately 176-09:46 UTC ERT).
This will be the first two-way gravity pass.
