Traffic Report  on 15 August '19

One object reported inside ten LD

One minor planet is reported inside ten lunar distances (LD) of our planet today. 2019 PJ is inbound from 9.31 to 8.74 LD.

This report was generated at 1822 UTC with today's DOU MPEC posting from June first follow-up for 2019 LQ1, adding 9.13 days to its 2.00-day discovery arc, and astrometry from May for distant 478784 2012 UV136.



Notes: Ten times the distance to the Moon (ten LD) has no astronomical importance but is a useful boundary for reporting about transient natural objects that approach our planet's gravitational sphere of influence (SOI), which has a radius of about 2.41 LD from Earth's center. This puts a focus on some of the most important and very best NEO observation work, representative of the much larger NEO discovery and tracking effort. "Distant" is used here to describe an object under observation that has come within ten LD since A/CC began this traffic reporting (2007) but is not now so close. Object temporal distances are derived by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.

NEOCP Activity  on 15 August '19

The MPC's NEO Confirmation Page has 14 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had fourteen objects listed. Of these, four were "one nighters." So far The Tracking News has counted a total of 23 listings on the NEOCP today.

To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
