Observing Run of (436724) 2011 UW158 on 2015-06-20
On 2015-06-20 I ran a series of 30 -- 60 Second Luminance BIN2 Images on itelescope.net's (TEL T9 0.32-m f/9.3 Ritchey-Chretien + CCD + f/7.4 focal reducer) at Siding Spring Observatory, Coonabarabran, NSW, Australia. (MPC Q62) and did data reduction on four images.
