Called Eric and helped opened mirror covers. Running on tanks for the weekend to prevent problems. Once opened, weather was great. Had an issue with one target and checking spectra with osqlsp. Curious why only wavelength graph wouldn't display. restarting program didnt help other data was taken and worked fine so no loss Closed mirror covers at end of night then opened again to double check closing in correct configuration ------------------------------ Submitted on 2016 Nov 19 [7:06:45]
