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.

Confirmation Images of the Near-Earth Object 2015 LF on 2015-06-07

The Near-Earth Object 2015 LF (Orbit type: Apollo ) was first observed by the Catalina Sky Survey(MPC code 703) on 2015 06 07. The asteroid has an approximate diameter of 13 m - 31 m ( ~45 foot - 102 foot) ( H=26.4) and will make a close approach to earth on 2015-Jun-08 at ~ 23:49 UT (06:49 PM CDT) at an approximate distance of 0.00131Astronomical Units ( 0.51 Lunar Distances) or 121,772.108 Miles (195,973.211 KM).

While 2015 LF was on the NEO Confirmation Page in an effort to help in the confirmation I ran three series of 30 -- 10 Second Luminance BIN2 Images on itelescope.net's (TEL T27 0.70-m f/6.6 CDK astrograph + CCD) at Siding Spring Observatory, Coonabarabran, NSW, Australia. (MPC Q62) and created 4 stacks 15 images (run number one was not used due to poor sky).

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.
