Gangphase adjustments over owl shift

Log Number: 4481283Logbook(s): Entry Makers: jhowardBody: 

Excluding the time we adjusted the gangphase when check the orbit to Hall C after the 2nd pass separator tripped, we had to adjust gangphase 12 times. As the night went on we had to adjust it less, maybe because of the outside temp stabilizing, though the phase was still drifting, it just seemed to recover back to where it was.

We did notice that the beam spot on the 1A SLM would stretch in a pattern, like it had a low energy tail on one side, and then flatten out on the other. The energy lock increased on both ends.

No idea what cause it yet.
