Confirmation Images Of The NEOCP(NEO Confirmation Page) Object (A10aElq = 2002 XQ90) on 2018-12-13

The NEO 2002 XQ90 first observed at an apparent magnitude of 17.4 by Lincoln Laboratory ETS, New Mexico(MPC Code 704) on 2002-12-15, ten days after it made a approaches of 11.50 Lunar Distances (0.02954 Astronomical Units). This asteroid was observed until 2003-01-12 when it became too faint to be observed. On 2018-12-09 ATLAS-MLO(Asteroid Terrestrial-impact Last Alert System - Mauna Loa) on its nightly sweep of the nigh sky found an object at an apparent magnitude of an apparent magnitude of 19.1. Observations of this object were reported to the Minor Planet Center(MPC) using the observer-assigned temporary designation A10aElq. The object was posted the NEO Confirmation Page. Observer from around world submitted confirmation observations to the MPC. In an effort to help in the confirmation I obtain 60-10 Second Luminance BIN2 taken using iTelescope.net's(T11).

I use Astrometrica to do the data reduction by way of the stack and track method. I had Astrometrica stack 4 sets(stacks) of 14 images.

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.

The of Confirmation of the Asteroid the 2018 PL9

On 2018-08-07 at ~ 10:30 UTC observers with ATLAS (Asteroid Terrestrial-Impact Last Alert System) imaged a "new" asteroid. Over the next ~ 35 minutes, the ATLAS term would take three additional observations. The observations were submitted to the Minor Planet Center(MPC) in Cambridge, Massachusetts using the observer-assigned temporary designation A107TVP. This "new" asteroid was posted to the NEO Confirmation Page(NEOCP) informing observers around the world that "A107TVP" needed confirmation observations.

About five hours later I checked the NEOCP saw A107TVP listed(by this time it had "precovery" observations from Pan-STARRS 1, Haleakala.), and decided to take confirmation images. I had iTelescope.Net's T30 to started taking 60 second luminance BIN2 images and was able to obtain 28 images. I use Astrometrica to do the data reduction by way of the stack and track method. I had Astrometrica stack 3 sets(stacks) of 9 images. Each image was shifted match movement of A107TVP.

I submitted four observations of 2018 KE3 to the The Minor Planet Center(MPC) in the "new" "Astrometry Data Exchange Standard (ADES)" format [PSV -"Pipe Separated Values"]

On 2018-08-05 the MPC published "MPEC 2018-P10 : DAILY ORBIT UPDATE (2018 AUG. 5 UT)" containing my 2018-08-04 observations. of 2018 KE3.

As more observations are made(over time) of any given asteroid.---more accurate orbital elements can be computed (with lower uncertainties). Here a test with Find_Orb showing "small" improvement to the orbital elements for 2018 KE3 (before and after my 2018-08-04 2018-08-04 observations).

If one would to keep their eye JPL Small-Body Databas day afer day they see this
"improvement" of orbital elements and lower uncertainties as well.
