                 ------------- ACTIVITY LOG --------------
 Observing Specialist: N.C.Hastings
    I opened tonight at 18:30 to allow for cooling. Clouds were present then
cleared off at sunset, only to return at twilight end. We closed for clouds
at 21:43 and humidity as well. We opened again with high humidity at 23:50
and remained so with variable clouds.
    Second half remained mostly clear with lower humidity and decent seeing.
No troubles other than the standard Remark million arcsec offset bug but it
did not interfere. All ran smoothly.
