              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Night was clear except for some thin clouds near morning twilight.  The seeing was variable, sometimes approaching 3".
Had two potential issues with the DIS guider.  While running the focus loop, the guider thought the star was where there was no star (around image 312). It was definitely trying to measure that empty space, because the measurements were nonsense.  Later, at 05:20 we noticed that the guider had shut itself off for no reason and with no warning.  It was definitely running before, and there were no sounds for it turning off.
