              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden
Night was plagued with thick non-threatening clouds.  The first half was mostly clouded out, although they kept trying.  Clouds cleared up just before the switch, and stayed away until the last hours.  When clear, seeing was just above 1".  No other problems to report.
