Hello

I did not have jury duty today, so I was here to watch the pass.

Periapsis 398 occurred at DSS 15.  The station had no problem locking up
two-way.

Times of interest (all UTC ERT):

181/17:09:38 Switch to LGA
181/17:14:20 Receivers in lock on LGA two-way
181/17:20:13  ISH - begin slew to NADIR
181/17:52:13 Periapsis 398
181/18:04:15 ISH - begin rollout
181/18:05:00 Receivers out of lock
181/18:24:15 ANS
181/18:36:07 Switch back to HGA

This was the last two-way gravity pass.  The next one-way gravity pass is
Periapsis 402 (approximately 183/16:25:43 UTC ERT).
