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 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).

The Asteroid 2018 KE3 [NEO(Amor)] on 2018-08-04

The Asteroid 2018 KE3 is an Amor (a Near-Earth asteroids whose orbits approach but does NOT cross Earth's orbit) with an estimated diameter of  400 M to 900 M(1312.34 Foot to 2952.76 Foot)  its MOID (Minimum orbit intersection distance) is 0.213016 AU(82.9 Lunar Distance (LD))

On 2018-08-04 I was able to obtain 40-60 Second Luminance BIN2 Images on itelescope.net's (T17 TEL 0.43-m f/6.8 reflector + CCD).

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).
