Problems:
During the afternoon calibration and night observations, we had serveral SISPI alert of CCD missing extension XX, and then followed with an interlock error. Restart SISPI solve the problem. The exposures effected by this error includes:
706943, 707011, 707012, 707049-707052, 707054-707056,707120-707125
We restarted SISPI twice in the afternoon and once during the night.
17 min was lost due to the problem and the restart during the night.
At 1:40 CLT, SISPI alarm due to DECal, 3 min lost.
