              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had clouds and some light rain at the start of the night, and then mixed waves of clouds and clear sky.  CU03 missed their eclipse and so allowed CU10 to start early.
I considered closing at various points but we were able to keep going until shortly before morning twilight, and got spectra of a fair number of targets.
