	00:55-03:35	02:40	Multiple issues with the lower portion of mirror. Caused long stacks while trying to find segments and adjust for piston of many segments. Segments with a correction of 100 in piston: 7:2 5:2 5:1 Lost segments: 4:1 5:1 and 6:1 All were looked for in a variety of ways. ATM helped me located 6:1 over the phone. The other two segments were very far off. Possibly out of view on HEFI as I tried searching HEFI for about 10 minutes with no luck. ATM was able to find these two segments when she came up. Segment 5:2 piston moves makes loud, high pitched sounds when moved. ATM is aware of the issue.	Called: Amanda Talked on the phone for a bit and tried various techniques. Came up and we were able to get everything pistoned into place and locate all lost segments.
	09:10-09:12	00:02	When moving to a new target, the dome and tracker started moving but the structure never lifted up.	Canceled the trajectory and resent it. Structure lifted this time.

Ops Comments	none

TO Comments	A number of issues with the mirror array combined with a large temperature drop led to time constraints with grabbing HEFI measurements. Otherwise, clear and chilly night.
