SN2012ca [EFOSC: Ugriz] - Followup
Seeing ~1.0".

Seeing ~0.9". Had to change rotator angle to get rid of the noise in the upper right quadrant. 
Hip091690 Observed before and after the target (observed twice after the target because of the noise problem).
*** Noise problem continues. TO had to go to the telescope to fix it. ***
