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 49 images from T24. I use Astrometrica to do the data reduction by way of the stack and track method. I had Astrometrica stack 3 sets(stacks) of 14 images. I had work around the meridian flip.

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 2018-09-09 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).
