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).
