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 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).

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.

The Near-Earth Object(Orbit type: Apollo ) 2015 AZ43 was first observed by Pan-STARRS 1 on 2015-01-11 and has been listed as a Virtual Impactor by SENTRY (JPL). 2015 AZ43 has a VERY SMALL impact risk(0.012%) for the date 2107-02-27.19. With more observations this risk could be rule out.

The Asteroid 2015 AZ43 On 2015-02-06 From Mayhill, New Mexico (New Mexico Skies) - MPC H06

The Near-Earth Object(Orbit type: Apollo ) 2015 AZ43 was first observed by Pan-STARRS 1 on 2015-01-11 and has been listed as a Virtual Impactor by SENTRY (JPL). 2015 AZ43 has a VERY SMALL impact risk(0.013%) for the date 2107-02-27.19. With more observations this risk could be rule out. In an effort to help improve the orbit I made two imaging run from Mayhill, New Mexico (New Mexico Skies) - MPC H06 using itelescope.net's(TEL T11 0.50-m f/6.8 astrograph + CCD + f/4.5 focal reducer) on 2015-02-06.

The Asteroid (357439) = 2004 BL86 On 2015-01-25

The NEO (357439) 2004 BL86 (Orbit type: Apollo ) (estimated to be 440–1000 meters in diameter) will safely make a Close-Approach of 3.1 Lunar Distance on 26 January 2015. This will be the closest known Approach by something this large (H = 19.0) until 2027, and will briefly peak at around apparent magnitude 9.0 It has been schedule for Goldstone Observations(2015 Jan 27-Feb 1).
