Hello

Periapsis 377 occurred at DSS 65. The station had no problems locking up.

Times of interest (all UTC ERT):

171/12:39:25 Switch to LGA
171/12:44:28 Receivers in-lock
171/12:50:00 ISH - begin slew to NADIR
171/13:22:00 Periapsis 377
171/13:34:02 ISH - begin rollout
171/13:38:10 Receivers out of lock
171/14:05:54 Switch back to HGA

The next MOLA and Radio Science gravity pass is Periapsis 380.  Periapsis
time is 173/00:19:32 UTC ERT.

Paula

Trish:
Thought you would like to know that MOLA successfully tracked across the
pole on p377 when the s/c was tilted off nadir by some 49 degrees.  Signal
was weaker than normal and we only acquired about 4 minutes of data but it
was centered on the cap (we think we reached 89.9? N) and we "filled the
hole".  Waiting to download p380.

Thanks for all your help - we are going to need that tracking across the cap.
