              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We opened once and had just enough time to focus before thick clouds moved in.  Then opened again and had just enough time to observe one standard star, before more clouds and threatening radar moved in.  The clouds and/or radar continued to haunt us for the rest of the night.
