Observing Run of 2015 PU228 on 2015-08-24 from Nerpio Spain

On 2015-08-24 I was able to obtain 17 -- 60 Second Luminance BIN2 Images on itelescope.net's (TEL T7 0.43-m f/6.8 astrograph + CCD) at AstroCamp Observatory. Nerpio, Spain (MPC Code I89) and created 3 stacks of 5 images

Observing Run of 2015 NK13 on 2015-08-22 from Nerpio Spain

On 2015-08-22 I ran a series of 45 -- 60 Second Luminance BIN2 Images on itelescope.net's (TEL T18 0.32-m f/8.0 astrograph + CCD) at AstroCamp Observatory. Nerpio, Spain (MPC Code I89) and created 4 stacks of 10 images ( in one the stacks had star where 2015 NK13 should be and was not use)

The Asteroid 2015 AZ43 On 2015-02-14 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(0.012%) 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 ran a imaging run from Mayhill, New Mexico (New Mexico Skies) - MPC H06 using itelescope.net's(TEL T21 0.43-m f/6.8 astrograph + CCD + f/4.5 focal reducer) on 2015-02-14.

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.
