Confirmation Images of the Near-Earth Object 2015 PK9 on 2015-08-10

The Near-Earth Object 2015 PK9 (Orbit type: Apollo ) was first observed at SONEAR Observatory, Oliveira.(MPC code Y00) on 2015 08 10.10036. The asteroid has an approximate diameter 49 m - 110 m ( Absolute Magnitude: H= 23.651). This asteroid made a close-approach to Earth on 2015-08-07 Nominal Distance (AU) : 0.0148213183067307 (5.768 Lunar Distances). The asteroid's Earth MOID (Minimum Orbit Intersection Distance) is 0.013686 AU (5.326 Lunar Distances). The last published Observations was made at: 2015 08 11.54955. At the time of this 122 observations have been made and the orbit has as uncertainty of 6.

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.

Astrometrica object verification window( for 1 of 30) 60 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) (see NOTE below on digital artifact.)

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.
