              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started with some clouds but they were never much of a problem as we were pointed on a clear portion of the sky.  Everything ran really smoothly, no echelle issues.  Until I dismounted ARCTIC and found that the filter wheel was misaligned. It looks like that after have many filter changes over the course of UV02’s time the wheel became slowly misaligned.  *sigh*
