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 three observations of A107TVP to the MPC in the "new" "Astrometry Data Exchange Standard (ADES)" format [PSV -"Pipe Separated Values"] at 2018-08-07T18:00:23.907Z. I got the automatic acknowledgement e-mail at 18:03 (UTC) and an "Automated NEOCP candidate posting results" e-mail at 18:11 (UTC).

On 2018-08-08 I took and submitted three additional 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 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).

The Recovery on 2nd Opposition of the Asteroid 2011 YS62 From 2015-09-26 To 2015-09-28

Observing Runs Looking for 2011 YS62 from 2015-08-26 to 2015-08-28

When it comes to target selection there two criteria I use first is would additional observations be useful, the second is the target in range of the telescope's capability. To find targets I check one or all of the lists (see below) and see if the target is range of the telescope's capability (if it is important I will push the limit of the range) Then I will plan an observing run. Recently I checked the Arecibo Asteroid Schedule and I saw they had requested optical astrometry for 2011 YS62. At the time this asteroid had a data-arc span of 89 days and had been unobserved for 1314 days (3.597 years)

First Night

I first did run of 15 - 120 Second Luminance BIN2 Images on itelescope.net's (TEL T27), with no luck,. Next I used Find_Orb to generate new orbital elements with Epoch 2015 Sep 26.0 and did a another run 15. I also used Find_Orb's Monte Carlo function to generate a lot of clones(virtual asteroids) orbital elements and then manually add them to Astrometrica's MPCOrb.dat file. Then I created 3 stacks of 5 images and found a moving object near the known object box of one of the clones. I assigned a temporary designation to the object and submitted night one's observations to the Minor Planet Center.

Second Night

Using Find_Orb I generated two orbits one was with just night one’s observations, the other with 2011 YS62 and night one's observations (“updated orbit”) and manually replaced the "clones" orbital elements. Next I ran a series of 6-120 Second Luminance BIN2 Images on itelescope.net's (TEL T27) and created a stacks of 5 images and found an object at the known object box for the "updated orbit". Then I ran a second run of 6 images and created a stack of 5 and saw that the object was moving. Later on I ran another run of 15 images and created a 3 more stacks of 5 images. I assigned a (new) temporary designation to the object and submitted the second night’s observations to the Minor Planet Center. Shortly thereafter the object was listed on the NEO Confirmation Page.

Third Night

I did the same orbit update has I did the night before then, I obtain 32--120 Second Luminance BIN2 images with itelescope.net's (TEL T27) and created 3 stacks of 10 image and submitted the third night observations to the Minor Planet Center using the designation that was on the NEO Confirmation Page.

On 2015 Sept. 28 the Minor Planet Center issued MPEC 2015-S102: 2011 YS62 with the observations from the three nights of and updated orbital elements.
