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 2018-09-09 2018 RQ1 as a data-arc span of 31.5 hr with 22 published observations. 2018 RQ1 is listed on the NASA/JPL Sentry and NEODyS CLOMON2 risk pages.(as of 2018-09-09) In an
effort to help with the improvement of the known orbit I had iTelescope.net's(T30) start taking images and was able to obtain 22-30 Second Luminance BIN2. I use Astrometrica to do the
data reduction by way of the stack and track method. I had Astrometrica
stack 3 sets(stacks) of 7 images. Each image was shifted match the movement
of 2018 RQ1.

Confirmation images of the NEO 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. It was posted to the NEO Confirmation Page(NEOCP) under the observer-assigned temporary designations "ZR388AE" In an
effort to help in the confirmation I obtain 60-30 Second Luminance BIN2 taken using iTelescope.net's(T31).
I use Astrometrica to do the data reduction by way of the stack and track method. I had Astrometrica stack 3 sets(stacks) of 20 images. Each image was shifted match movement of 2018 RQ1(ZR388AE).
I submitted my observations to the Minor Planet Center(MPC). On 2018 Sept. 8 at 21:42 UTC the MPC Issued MPEC 2018-R63 : 2018 RQ1 assigning the objet the provisonaldesignation 2018 RQ1.

The Flyby By a "Astronomical Yard" of 2012 TC4
On 2017 October 12, the asteroid 2012 TC4 will flyby the Earth. This flyby has received a great deal of coverage in the media. When comes to media coverage of any asteroid flybys one of the most overused expressions is "close shave." Anyone who ever had to shave for work knows what a close shave is and what one is not. By comparing the solar system to the known universe, Pluto would be a "close shave" astronomically speaking. However, the subject at hand is the flyby of the Earth by an asteroid, therefor the Earth may serve a useful point of comparison.
If one wishes to simplify the matter, one could create a scale model of the Earth by way of a spreadsheet. If, one uses a ball with a diameter of 29.21 cm (11.5 inches) [this happen to be same as the as the length of a football ball(American)] to represent the Earth:
- A CM would be 436.2204724 KM, an inch would be 1108 KM.
- The International Space Station would be 9.2 mm away.
- Geosynchronous orbit would be 820.4 mm, 0.8204 m, or 0.8972 yards
- 2012 TC4 Nominal Distance(JPL)[2017-Oct-10] would be 1003.6 mm, 1.0036 m, or 1.0976 yards
- Light-second would be 6872.5 mm, 6.8725 m, or 7.5159 yards
- Lunar distance would be 8666.1 mm, 8.6661 m, or 9.4773 yards.
