Near-Earth Object (436724) 2011 UW158 on 2015-06-14

Background 

The Near-Earth Object (436724) 2011 UW158 (Orbit type: Amor [PHA]) was first observed by  Pan-STARRS 1 (MPC Code F51)  on 2011-10-25. This asteroid has an absolute magnitude of 19.4 which would give it an approximate diameter of 350 m to 780 m (1148.29 feet to 2559.06 feet).


(436724) 2011 UW158 will safely make a close approach to earth on 2015-July-19

Asteroid radar observations have been schedule for (436724) 2011 UW158 2015 Jul 13-26 at Goldstone 2015 Jul 12-17 at Arecibo with the goal of high resolution imaging.

Observing Run on  2015-06-14

On 2015-06-14 I  ran a series of 30 -- 60 Second Luminance BIN2 Images on itelescope.net's (TEL T09 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 six images.

NOTE: A digital artifact appeared in three images (1,2,and 3) "near" (436724) 2011 UW158 however it was within 0.3 a pixels of have the SAME Pixel Coordinate (x/y) in ALL three images -- I dither the images so this could ruled out-- it being anything in orbit.
