Traffic Report  on 2 October '19

Nineteen objects reported inside ten LD

Bulletin - 2303 UTC:  One new discovery of a close passer has been announced.

Nineteen asteroidal objects are reported within ten lunar distances (LD) of our planet today. Three are inside Earth's sphere of gravitational influence. Risk-listed intruder 2019 SP3 enters the SOI, moving from 2.64 to 1.10 LD, 2019 SD8 comes its closest to Earth on this passage, reaching 1.39 LD, and risk-listed intruder 2019 SM8 exits the SOI, flying off from 1.40 to 4.52 LD.

This report was generated at 1920 UTC with five discoveries. See the active traffic tables above and below for details about approaching 2019 SV9 (MPEC) and three risk-listed outbound objects: 2019 TA (MPEC), 2019 TB (MPEC, DOU), and intruder 2019 TD (MPEC). The fifth discovery is already departed intruder 2019 TE (MPEC), which is preliminarily calculated to have passed us at about 0.9 LD on September 28th (approach uncertainty +/- 1.52 hours). Today's DOU MPEC has follow-up for inbound risk-listed intruder 2019 SP3 and departed objects 2019 SO8 and risk-listed 2019 SC.

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. Object temporal distances are derived by A/CC from JPL Horizons data. "LD*" indicates some uncertainty in object passage time and distance. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.

NEOCP Activity  on 2 October '19

The MPC's NEO Confirmation Page has 63 listings

When last checked at 2330 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 63 objects listed. Of these, 35 were "one nighters." So far The Tracking News has counted a total of 98 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.

Impact Risk Monitoring  on 2 October '19

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS at 2330 UTC)
See the CRT page for a list of all objects rated recently as risks and our ephemerides page for a list of risk-listed objects under current observation.
The time horizon for JPL and NEODyS listings is 100 years, and both post impact solutions beyond that for some special objects.
For the latest official risk assessments, and for explanations of the terminology, see the NASA/JPL Sentry and NEODyS CLOMON2 risk pages.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" to learn more.
