Comet 21P/Giacobini-Zinner on 2018-09-14 from Mayhill, New Mexico


Comet 21P/Giacobini-Zinner on 2018-09-14 from Mayhill, New Mexico [New Mexico Skies](MPC Code H06) 60-30 second luminance BIN2 images taken with iTelescope.net's (T11)

Credits

The targeting information was obtained from the
The Minor Planet Center (MPC)
http://www.minorplanetcenter.net/

The images where taken with iTelescope.net's
(TEL T11 0.50-m f/6.8 reflector + CCD + f/4.5 focal reducer)Mayhill, New Mexico [New Mexico Skies](MPC Code H06)

http://iTelescope.Net/

The observations were made in support of the PACA_21/GZ campaign

https://www.facebook.com/ThePACAProject/

Image blinking and 1st stacked image was done with CCDStack2

Data reduction, the stacked images, and the object verification windows was done with Astrometrica

http://www.astrometrica.at/

The data was examine with the help of
Find_Orb Orbit determination software - Project Pluto

More Follow-up Observations of 2018 RQ1


The NEO(Aten) 2018 RQ1 (approximate diameters 39 m - 88 m [127.953 foot - 288.7139 foot]) was first observed by the Catalina Sky Survey on 2018-09-07. As of 2018-09-10 2018 RQ1 as a data-arc span of 72.77 hr with 44 published observations. 2018 RQ1 is listed on the NASA/JPL Sentry and NEODyS CLOMON2 risk pages.(as of 2018-09-10) In an effort to help with the improvement of the known orbit I booked imaging runs on iTelescope.net's T11 and T24 of 60-30 second luminance BIN2 images each.

I was able to obtain 20 images from T11. I use Astrometrica to do the data reduction by way of the stack and track method. I had Astrometrica stack 3 sets(stacks) of 6 images. Each image was shifted match the movement of 2018 RQ1.

I was able to obtain a  set of  4-60 second luminance BIN2 images taken with iTelescope.net's (T30) and a set 12-60 second luminance BIN2 images taken with iTelescope.net's (T30). I use Astrometrica to do the data reduction by way of the stack and track method. I had Astrometrica stack 3 sets(stacks) of 3 images.  Each image was shifted match movement of ZTF00Th.

The NEO 2016 WJ1 on 2016-11-28 from Mayhill, New Mexico

See The NEO 2016 WJ1 Has Been Removed from the Sentry Risk Table--Neodys Risk Table List 3 Possible Impacts 2106-2115.

NOTE with only 8 days data-arc span there is "little" known about the NEO 2016 WJ1 and the information in this post may become outdated. So one should always check the links for updates. Whenever an object is posted to one the risk lists (especially if it has a Torino Scale 1 or greater) and it is observable, observers will take a particular interest in it. In the coming days it is possible there will be more follow-up observations and a search in archives for precovery observations. It is MOST likely this object will be removed from the risk lists. It could take observations over one or more orbital periods before we can reliably say where it will be from 2030 to 2108.
