Hello,

Periapsis 380 occurred at DSS 45.

Times of interest (all UTC ERT):

172-23:36:55  switch to LGA
172-23:41:51  receivers in lock on LGA signal
172-23:47:32  ISH - begin slew to NADIR
172-00:19:32  Periapsis 380
172-00:31:34  ISH - begin rollout
172-00:35:32  receiver out of lock before this time
172-00:51:34  ANS
172-01:03:25  switch back to HGA

-Trish

Dick:

FYI, according to Greg Neumann, we are missing quaternion data
for periapsis pass 380, one of the MOLA roll passes. This would
also be an RS issue, since any RS data collected during these rolls
has to be properly corrected with quaternions and location
of the antenna wrt the center of mass.
