Plenty.
-Tried the EarlyTime keyword in ScriptEditor, and it does not work. The telescope waits beyond the designated time.  To get the control back, you must press Abort and wait about 30 seconds for the system to respond and come back.

-At the start of an hour angle sequence, it doesn't make sure the telescope is positioned before it starts the exposures.

-In watching what happens when the HA/Dec/tracking-off images are taken, the dometracking turns off first and then the telescope tracking (separated by a split second).  It would be preferable if dome tracking stays on when telescope tracking is turned off.  The dome tracking does not automatically turn back on after an hour angle sequence, and must be manually turned back on. It also does not come back on when a sidereally tracked image starts.  We are also concerned that the dome tracking may be turned off any time you enter an hour angle/dec, e.g. if you commanded an HA for a large slew the dome would not be in the correct position when the exposure starts.

-Two errors occurred during an exposure, a few hours apart in the night, during exposures 329779 and 329308, and coincided with the DTS values plummeting in the ImageBuilder plot in the Telemetry Viewer.  The no Interlock errors appeared in the Observer Console, Alarm History, or Architect Console GUIs either of these times (all lights stayed green, even after a GUI refresh, and Reset a few times). Then we tried to Configure and then saw the Interlock errors when the Configure hung up.  For the second case, we tried Stop Exposure Loop, Abort, and Configure after the exposure hung and Exposure Queue stopped sending exposures to the instrument. Alistair did some poking around and found ICS Interlock errors associated with DHSB.

- We tested a pure HA script which turns off dome track, starts the first exposure, then starts moving the telescope to the right position, but keeps taking observations... all very strange. We had the TO turn telescope tracking and dome tracking on manually to get to the dome to the right position, then turned telescope track off for the rest of the expsosures. Notably the script kept taking images this whole time. SUMMARY: You cannot turn dome tracking on if the telescope tracking is off. Can this be corrected?

- At the end of the night, we configured the OCS which should turn the DTS back on, which we turned off earlier due to problems with the system crashing.

TIME: Lost 50 minutes of observing time due to failures
