Proposal #69

I would like SRO-50 to observe the field of SDSS J160111.53+091712.6 with Three I,R,V,B,B,V,R,I sequence on 4 nights with as many different EXPTIMES as necessary to cover the magnitude range from 12.8 thought at least 18.0. with Single filter uncertainties 0.05 or less. The purpose of this is to obtain better field calibration data relating to a recent sequence that was prepared for the target star. NOFS data for the area is single night only. Much of the existing APASS data has errors in neighborhood of 0.1 magnitudes I V.
FOV 20’ x 20’ minimum
FOV Center RA: 16 01 11.53
FOV Center DEC: +09 17 12.6
Mag range 12.8 - 18.0 minimum.
Chart ID: X18357SL
Sequence Table ID: X18357SO
