The Asteroid 2015 AZ43 On 2015-02-07 and 8 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(0.017%) 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 two nights one 2015-02-07 and the other on 2015-02-08.
