(* means a trouble report has been issued or appended to)
The dome was not opened tonight, primarily due to dust, but also due to
threatening weather late in the evening.
Both the azimuth and elevation continue to overshoot, but not in any
predictable fashion.  Further testing was done today with analog plots
obtained for the azimuth azis.
