(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.

Confirmation Images of the Near-Earth Object 2015 KQ154 on 2015-05-26

The NEO 2015 KQ154 (Orbit type: Amor) was first observed at SONEAR(Southern Observatory for Near Earth Asteroids Research) Observatory, near Oliveira, Brazil on 2015-05-25 by C. Jacques, E. Pimentel, J. Barros. While it was on the NEO Confirmation Page in an effort to help in the confirmation I ran a series of 20 -- 30 Second Luminance Images BIN2 on iTelescope.Net's Telescope-09 , at Siding Spring Observatory, Coonabarabran, NSW, Australia. (MPC Q62) on 2015-05-26 from 15:43(UTC) to 15:57(UTC) and did data reduction on five images.
