Confirmation Images of COMET P/2015 F1 (PANSTARRS) On 2015-03-22

COMET P/2015 F1 (PANSTARRS) WAS discovered on 2015 03 21 by the PANSTARRS sky survey. While it was on the PCCP Confirmation Page in an effort to help in the confirmation I made follow-up measurements on March 22, 23, and 24 from Siding Spring Observatory, Coonabarabran, NSW, Australia.(MPC Code Q62)


Here is a video of COMET P/2015 F1 (PANSTARRS) 28-60 Second Luminance BIN1 Images, taken with iTelescope Net's Telescope T27 (TEL T27 0.70-m f/6.6 CDK astrograph + CCD) 2015-03-22 16:43 UTC to 17:37 UTC. (C) Steven M. Tilley http://lagniappeobserving.blogspot.com/

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 2015-02-13 from Auberry California USA - MPC U69

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 Auberry California USA - MPC U69 using itelescope.net's (TEL T24 0.61-m f/6.5 astrograph + CCD) on 2015-02-13.

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.

The Carina Nebula (NGC 3372)--A work in progress with more progress

Just for kicks I am trying to image  something "outside" our solar system. Today(2015-02-07) I added more data to the image.
