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.

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 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.

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.

  • (E23) Arcadia,NSW, Australia.

  • (T05) ATLAS-HKO, Haleakala, Hawaii,US.
  • (X31) Galileo Galilei Observatory, Oro Verde, Argentina.
  • (X74) Observatório Campo dos Amarais, Brazil.
On 2018-08-10 at 15:24 UTC the MPC Issued "MPEC 2018-P46 : 2018 PL9" assigning the provisonal designations "2018 PL9" to the "new" asteroid.

A Rock Designated ZLAF9B2(now 2018 LA) Social Media and Fireball Reports

On  2018-06-02 Richard A. Kowalski, with the Catalina Sky Survey reported observations of a "new" object, given  the observ3er-assigned temporary designation "ZLAF9B2", to  Minor Planet Center in Cambridge, Massachusetts, USA.  It was posted to the NEOCP(NEO Confirmation Page) making the observations available to asteroid and comet  researcher around the world.   The data was analyzed and posted JPL's Scout: NEOCP Hazard Assessment, independently analyzed and posted to Bill Gray's  Current NEOCP summary page. Then emails  to mailing list post to social madia started going out. It was know to be small at the start.

When wroke up on 2018-06-02 I check iTelescope.net and saw their facility in Siding Spring Observatory, AU was clouded out than I went out to eat breakfast.  When got back just to see what I would observe if I could observe, I check the NEOCP and saw that ZLAF9B2 was "bright",  and  then  check "The Minor Planet Mailing List {MPML}" Some of the asteroid and comet researchers where talking.  The Bill Gray sent and a number of  carefully worded emails to email list  stating ZLAF9B2 should be a "Priority Target".
 
One of the programs available to asteroid and comet researchers is Find_Orb it is useful for calculating approximate ephemeris, determining approximate orbits, residuals,  generating virtual asteroids, virtual impactors, predicting impact locations, and many other things.  It should be noted  IF one uses wrong setting one get a totally wrong solution. One things Find_Orb can be use for is generating a "asteroid risk corridor" with the help of Guide 9.1. This should be done with care because of uncertainties in  observations how one sets the over-observing parameters as well with other setting can the effect the results.  Bill Gray posted post a risk corridor for ZLAF9B2 and I thought I would give it a try. I had Find_Orb generated  virtual asteroids and virtual impactors using a  monte carlo process. 


Here is my TEST with Find_Orb using a monte carlo process see the files here

Here is my TEST with Find_Orb using a monte carlo process see the files here
Before I share my results ZLAF9B2(now 2018 LA)  "impacted" the Earth over southern Africa creating a Fireball. around 2018-06-02 16:45 UT and posts about impact started making.  After the impact two (pre-impact) follow up observations from ATLAS-MLO(Asteroid Terrestrial-impact Last Alert System ---Mauna Loa) were posted to  the NEOCP(NEO Confirmation Page)  Then I did another  monte carlo process with the newly added ATLAS observations.
