Also Present: 
Hernan Tirado, Richard Kron
Problems: 
The VNC connection running on observer1 became unrespoinsive and froze. I think this may have been a faul with the "Exposure Table" window, as Chrome was continually displaying a message that is was not responding (with an option to Kill or Wait).

The machine was rebooted, and there initially some problems connecting to the VNC session running. No telescope/science operations were affected during this process. However the Exposure Queue would not accept further scripts. Hernan was able to re-connect to the VNC session and we were able to add new jobs to the exposure queue.

Some "unexpected behaviour" was noted when moving queued exposures around: when multiple-selecting exposures (SHIFT+) and dragging them, they would not be placed at the required point in a contiguous block. This means the user must select each exposure and move it.

NOTE .. for large parts of the night, the seeing was substantially greater than 3", which this form cannot report.
 

Comments: 

Just a "feature/usability" request that can be disregarded if considered unimportant:
Although there's flexibilityreating the scripts, for the user to specifty decimal/hh:mm:ss, perhaps it is useful for the Observer Console to convert any decimal-specified coordinates into hms? When there is a mix of the two in the exposure queue, it's harder to see at-a-glance if there will be an appreciable slew when moving from one script to the next.
