Various things failed and none of the planned observations could be obtained:

Telescope did maverick meridian flip that we cut short as it neared the floor.

The camera flatlined for none of the known reasons.

Then some part of the FW or rotary stage system got stuck. There is an issue with the large rotary stage acknowledged by several parties. I additionally think the FW can get stuck at times – witness the failed VE1 observations on JD 2455849.

PXI is at the moment unreachable over the internet following an iBoot power cycle that failed to re-boot the machine.
