Near-Earth Object 2015 JY1 on 2015-06-21

 Background
(as of 2015-06-21) 

Observing Run of 2015 JY1  on  2015-06-21

On 2015-06-21 I  ran a series of 60 -- 30 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.

Astrometrica object verification window ( for image 1 of 60)  30 Second Luminance BIN2 image taken with 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)

(MPC Q62)  (see  NOTE below on digital artifact.)
NOTE: A digital artifact appeared in two images (59 and 60) "near" 2015 JY1 however the "digital artifact" was within  a pixel of have the SAME Pixel Coordinate (x/y) in the two images -- I dither the images so this should ruled out-- it being anything in orbit.
