I restarted the software today so it is running and recording again. We had some issues with the tertiary mirror moving on us mid exposure. Not sure of the cause but homing the tertiary fixed the issue both times tonight. A separate email with all the details sent to the engineering staff. When I went to close the enclosure I discovered that the mirror covers and eyelids did not close as I had commanded them. I manually closed the covers and re-opened the NA2 eyelid for my observers cals. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- UW05 Echelle T/H 23:00 00:25 Star suddenly move off guider during exposure, I had to home the tertiary to fix.
