+Keep a log about weather conditions, which pass you observed, and telescope problems.  Follow the example on the pages at [wiki:MayallZbandLegacy/ObservingLogs] . Please make a note of when you make any changes to the focus (note the time and the image exposure number before/after the focus change), any changes to weather conditions (increase in wind speed, change in direction, changes in humidity, sky brightness, cloud cover, etc.). Please stay aware of the observing conditions. Go out an look at the sky yourself every few hours - do not rely solely on the computer monitors and telemetry. Don't worry - you will not be eaten; just carry a flashlight. Sing loudly, if that helps :)

+Please record any catastrophically bad frames (such as saturated frames, or where the telescope moved) in the bad_expid.txt file. This file is svn-checked-in at the end of the night.
