Problems: 

 

1) 21:32 local time. After taking junk exposure DECam_00173289 there was a temporary error 'supply pressure too low', reset but and everything was okay for a moment or two but now problem has occurred again. Restarting FCM role, re-configuring, this is fixed.

2) Issue with the standard star field scripts e.g some scripts did not define the RA and DEC position to slew to for the first exposure on the script. Also repeated the telescope position for each filter in a script caused TCS error message.

----

2nd half:

- Observer Consoler crashed several times (froze or displayed error message)

- guider GUI froze (but guider kept working); started a second VNC window, after a while, this one spontaneously started working again

- telescope goes "clunk" when crossing meridian (bad PSF and ellipticity); this leads to loss of guider info
