              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
High winds and dust at sunset delayed opening, but they dropped pretty quickly in time for the first program to get some observations.  Later in the night we had bad seeing, occasional clouds, and sometimes wind direction restrictions, but nothing so bad we needed to stop observing.
The observer for the last program had an emergency so I did some service observing.  The telescope and instruments worked perfectly.
