              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden
Night was mostly clear and productive.
Seeing on echelle and dis were decent, but tspec was all over the place.  It was very difficult to focus, and I ended up focusing by hand.  Even then, the seeing was almost 3".  The focus loop was unable to get a parabola with a good fit, and more than once the star drifted off the boresight and then the loop failed entirely.  I didn't trust the results the loop came up with, so tried by hand and didn't get much better.
