              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening was clear and still.  At 23:13, a vertical strip of light began to appear on the left edge of the echelle slitviewer images. Could not find a source of light leak, and it disappeared after installation of the MSSSO U filter and slit swap. Do not know if it will return when the filter has been removed. The echelle started returning zeros at 04:45, it needed a restart of the ecehelle-icc process and a nubs restart to get it to behave.  Aside from the 12 minute loss, all programs got thier full times.
