              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS was producing "blank" images (ie. biases or dark looking frames) for the wavecals during checkout.  I initialized the instrument and also homed the mask.  The slitviewer image looked fine (with and without light).  That didn't fix the problem.  I then tried moving the turret and it got lost.  I homed the turret.  This fixed the problem.
We lost site power at 06:16, just as Candace was starting her final echelle exposure of Venus.  On generator power now.  Tripped intermediate level collision stop button, but it just needed to be reset to bring the telescope back online.  I parked the telescope and closed up at that point.
