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.

2nd Half:

No problems.
