              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
At the start of the night, we had heavy overcast and a few almost-believable radar blips nearby.  So we delayed opening until the clouds were a little thinner.  They conitnued to be a challenge for a while but the echelle was able to cut through, and then during the second half the sky cleared up quite nicely.  Everything worked very well.
