Confirmation images of the NEO 2018 RP8

The NEO(Aten) 2018 RP8 (approximate diameters 320 m - 710 m [ 1049.87 foot -  2329.4 foot]) was first observed by ATLAS HKO (Asteroid Terrestrial-Impact Last Alert System)  on 2018-09-15. The observations were submitted to the Minor Planet Center(MPC) in Cambridge, Massachusetts using the observer-assigned temporary designation A108wr0. This "new" asteroid was posted to the NEO Confirmation Page(NEOCP) informing observers around the world that "A108wr0" needed confirmation observations.  In an  effort to help in the confirmation  I obtain 60-15 Second Luminance BIN2 taken using  iTelescope.net's(T21).


I use Astrometrica to do the data reduction by way of the stack and track method. I had Astrometrica stack 4 sets(stacks) of  15 images.  Each image was shifted match movement of  A108wr0.

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.

Artist's concept of a near-Earth object. ImageCourtesy NASA/JPL-Caltech
On  2017 Jan  7  at  7:39:30.24(UTC) the Catalina Sky Survey discovered an asteroid on route to buzz the Earth. They submit their observations to the Minor Planet Center(MPC) and the "object"(with their observations) was posted the NEO Confirmation Page.  Observers from around from the world took follow-up observations and on 2017 Jan  8 at 15:14(UTC) the Minor Planet Electronic Circular announcing the discovery. On 2017 Jan  9 at  ~12:49 (UTC) buzz the Earth at ~  0.5 Lunar Distances (LD) -- to put things in perspective"If" the Earth Was the Size of a Basketball this would be ~ 12.80 feet(3.90 meters)  away.
