 Observing Specialist: J.Dembicky
Az meas 580.5  was 579.0  changed n/c
Alt meas -635.8 was -637.0 changed n/c
Chkmv error when I went to rotate the tertiary at checkout to BC1.  Had to call Nick and he came
in and we locked the tert at NA2 for the night.  Since it was cloudy I counted the time loss due
to weather.
No telescope problems otherwise.
A productive night (2nd half at least) despite clouds.
