Traffic Report  on 1 November '13

Three objects reported inside ten LD

Three visitors are reported to be within ten lunar distances (LD) of Earth today. 2013 UJ9 comes its closest to our planet this time around, reaching 4.90 LD at 0802 UT, while intruder 2013 UX2 is outbound from 5.49 to 6.33 LD and intruder 2013 UV3 exits ten LD, traveling from 7.85 to 11.57 LD.

Up next, 2013 UE1 arrives inside ten LD on November 4th, radar target 2001 AV43 arrives on November 6th, and radar target 2013 NJ on November 19th.

This report was generated at 1505 UTC with follow-up in today's DOU MPEC for 2013 UE1 and departed 2013 UG1.



Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. Object distances are interpreted 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 1 November '13

The MPC's NEO Confirmation Page has 32 listings

When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 32 objects listed. Of these, 22 were "one nighters." So far The Tracking News has counted a total of 43 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 1 November '13

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2359 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 is 100 years from today and for NEODyS is usually the year 2090. Both also post impact solutions beyond 100 years for a few special objects.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program 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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
