              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Thick clouds and nearby radar returns kept us closed during first half.
When the clouds decided to clear they went away fast, and after that we
had several productive hours on the sky.  Everything worked well; there
was one large magnesensor correction, which took care of itself.  The
problem with tcam is resolved.  The echelle shutter is still misbehaving
and will receive attention tomorrow.
