Hello,

Once again, DSS 15 had a few problems locking up to the low signal level.

Times of interest (all UTC ERT):

161-19:53:09  switch to LGA
161-19:57:24  ISH - begin slew to NADIR
161-20:11:55  receivers in lock on LGA signal
161-20:29:24  Periapsis 357
161-20:41:26  ISH - begin rollout
161-20:51:47  receiver out of lock before this time
161-21:01:26  ANS
161-21:13:17  switch back to HGA

The next gravity pass is Periapsis 358 (approximately 162-08:09:00 UTC
ERT). (It's our turn for two in a row.)
