Observing Specialist: C.Gray
An excellent night of observing! CU02 had a new observer sitting in for the PI and they were able to get all their data after a little bit of training. We had excellent seeing until the wind shifted, but even then it wasn't  too bad. No clouds and we observed until twilight!
No problems tonight.
