Comment: 
The seeing for the night started at 2.7" or so and over the course of the night dropped to 1.2-1.3", with brief extremes higher (3")or lower (1.1"). Note 1" seeing or better is required for weak lensing analysis. The night started out photometric, but clouds rapidly covered sky starting at 3:40 am Chilean standard time. By 4:15 am Cloud cover extended horizon to horizon and shows no signs of clearing before twilight, so dome was closed for the night.
