Problem Reports
PR Number	Times	Time Lost	Description	Response
4500	03:08-03:09	00:01	H4 velocity fault
4284	03:13-03:14	00:01	TMCS failed to acquire trajectory error following H4 velocity fault.
4869	00:42-00:42, 05:34 - 05:51	00:17	During OPS trying to go to a south trajectory got an LX Trq limit sensor fault (first error may not have been the torque limit). Normal recovery was done. Occurred once again during night at 05:34; took the TO a little while to find all of the override buttons to fix it.

Ops Comments	none

TO Comments	The fix for the PFIP probe problem worked. We closed early for threatening humidity and clouds.
