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.

Over three days the following observatories  submitted observations of A107TVP:

• (711) McDonald Observatory, Fort Davis, Texas,US
• (850) Cordell-Lorenz Observatory, Sewanee, Tennessee, US 
• (E23) Arcadia,NSW, Australia.
• (F51) Pan-STARRS 1, Haleakala, Hawaii, US   
• (J04) ESA Optical Ground Station, Tenerife, Canary Islands, Spain
• (L01) Višnjan Observatory, Tican, Croatia. 
• (P93) Space Tracking and Communications Center, JAXA, Japan.
• (Q62) iTelescope Observatory, Siding Spring,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.
