                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was not opened, due to poor weather.
Tom Harrison was the observer for NM05, Rhodri Evans was the observer
for UC03, and I was the observer for PU01.
Everyone was clouded and/or rained out.
I examined the images Charles Corson had taken to check the DIS low
resolution grating repeatability.  In his set of images, line
positions varied by +/- 1 pixel.
I spent most of the rest of the night reducing a set of throughput
data from June 17th.
