Turned off Vsub at 1:00 as all previous exposures for the night had failed, unable to locate guide stars, and more clouds moving in.
Turned Vsub back on at 4:45 as clouds began to thin out. After taking one WF exposure (after a bias frame), SISPI lost contact with TCS. Re-configuring failed and so we restarted SISPI.
However, the problem persisted after repeated attempts at configuring and restarting SISPI. TelOps was unable to fix the problem after multiple attempts and called an end to the observing shift at 5:30.
