Hello,

Periapsis 392 occurred at DSS 15. The station had no trouble locking up
two-way.

Times of interest (all UTC ERT):

178-19:14:57  switch to LGA
178-19:24:25  receivers in lock on LGA signal TWO-way (approximate)
178-19:25:34  ISH - begin slew to NADIR
178-19:57:34  Periapsis 392
178-20:09:36  ISH - begin rollout
178-20:09:54  receiver out of lock before this time
178-20:29:36  ANS
178-20:41:27  switch back to HGA

The next gravity pass is Periapsis 393 (approximately 179-07:36 UTC ERT).
