                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
Clear with very thin cirrus all night.
At the beginning of the night, NA2 guider images no matter what gcam focus
value are elongated in the "X" direction. There is also a darker column on
the right.  I tried every combination of restarting gcam and gmech I could
think of (init, remap, nubs, power-cycling). I wasn’t sure if it was the
camera imaging or the filter wheel positioning, or what. Fritz logged on
and suggested binning. Although several other things happened in between,
I think binning other than 1x1 causes the elongation. No real time was
lost since we continued the whole time and the science exposures were
short enough not to really need guiding.
No other problems.
