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.

Helping With The Confirmation of the Mars-crossing Asteroid 2018 PO23
On 2018-08-13 I check the NEO Confirmation Page(NEOCP) and an object clalled ZTF00Th.
I was able to obtain a set of 4-60 second luminance BIN2 images taken with iTelescope.net's (T30) and a set 12-60 second luminance BIN2 images taken with iTelescope.net's (T30). I use Astrometrica to do the
data reduction by way of the stack and track method. I had Astrometrica
stack 3 sets(stacks) of 3 images. Each image was shifted match movement
of ZTF00Th.
Then I submitted this batch of 4 observation to the Minor Planet Center.
About 14 hours later I obtain a set of 60-60 second luminance BIN2 images taken with iTelescope.net's(T11) I had Astrometrica stack 3 stacks of 15 images ( note a star keep me from having 4 stacks of 15 images)
Then I submitted this batch of 3 observation to the Minor Planet Center.
After another ten hours I obtain a set of 60-60 second luminance BIN2 images taken with iTelescope.net's(T17) I had Astrometrica stack 3 stacks of 15 images ( note the first 9 images where on the "wrong" side of the meridian flip)
Then I submitted this batch of 3 observation to the Minor Planet Center.
After 110 observations, collectively made from 27 observatories from around the world, at Aug. 16.90, 2018 the Minor Planet Center gave ZTF00Th. the provisional designation 2018 PO23 and removed it form the NEOCP.

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.

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 use Astrometrica to do the data reduction by way of the stack and track method. I had Astrometrica stack 4 sets(stacks) of ten images. Each image was shifted match movement of 2018 KE3.
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).
JPL Small-Body Databas day afer day they see this
"improvement" of orbital elements and lower uncertainties as well.
