Also at his request we decided to switch the order of his program and the PU04 Shack-Hartman observations as he wanted to be on the sky as early as possible. Additionally, Cullen Blake decided to forego his scheduled observing this evening, given that SPIcam is still out of commission. No one else at Princeton wanted the time, so he (and I) offered it to Don. I was asked to do the observations for him. Things were routine during first half without any of the little surprises that have popped up in the previous couple of nights. Just before 02:00 we switched over for Shack-Hartman observations of SAO 56505 which was around az,el (67,63) at the time of observation.
