Except for the last quarter of the night, we were plagued by intermitent clouds. The data that we took from UT 3:20 - 4:30 is basically useless due to the high extinction from cloud cover. It became so bad that we stopped taking data from UT 4:30 - 05:05 when the clouds became transparent enough to see some of the brighter objects. So we effectively lost ~1.5 hours of data to clouds and approximately the first 3/4 of the night were significantly affected by clouds. This coupled with the near full moon resulted in small t_eff.
