              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
This high clouds for most of the night, sometimes interfering with photon gathering, but we never actually stopped observing due to clouds.
During checkout I found a severe problem with the tertiary mirror; one axis was failing to move at all.  Bill came in to help and after some searching found a loose connector.  Once that was fixed and everything was buttoned up again, the telescope and instruments worked well.
