I just ended my run on BZ UMa, after collecting data from 01:00 to 10:00 UT. Relative to the 12.049 mag star in the AAVSO .dat file I see a steady decline from v=11.45 to v=11.58 over the course of the run. A few small bumps and dips are apparent in the raw data in the 0.01 - 0.02 mag range, but nothing bigger. Shawn (DKS)
