                ------------- ACTIVITY LOG --------------
Observing Specialists: J.Dembicky
Echelle slitview cam didn't work during checkout
DISslit images  28-32 were bad, like lots of noise in half of the camera.
It cleared itself up when I went back to full frame and then I didn't see
it anymore (even in windowed mode).
 Clouds came in and closed us around 23:15.  A few sprinkles of rain fell
but not much.  Thick clouds the remainder of the night.
