Problems:
After afternoon reboot of SISPI, Vsub did not come up on backplane 4. A second restart cleared it up.
Attempted PTC scans, but had shutter problems (not closing during a readout). We also had wrong prop-id, so decided to try again another afternoon.
Another shutter error during standard stars. For some reason, inital HW reset did not work. A couple more eventually did work, and we were back on the sky. Lost about 45 minutes.

No problems.
