Traffic Report  on 2 November '13

Two objects reported inside ten LD

Two asteroids are reported inside ten lunar distances (LD) of Earth today. 2013 UJ9 is outbound from 5.09 to 6.00 LD and intruder 2013 UX2 from 6.33 to 7.18 LD.

Coming toward Earth 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 1735 UTC.

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 2 November '13

The MPC's NEO Confirmation Page has 49 listings

When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 49 objects listed. Of these, 24 were "one nighters." So far The Tracking News has counted a total of 55 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 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.





Notes for Today's Latest Risk Assessments
2013 TV135JPL Sentry20032032-204722.0e-05-1.66-1.661JPL #2 for the day: "Analysis based on 512 observations spanning 20.127 days (2013-Oct-12.9551 to 2013-Nov-02.08213)." Diameter approximately 0.450 km. from mean, weighted H=19.4.
NEODyS17302032-204726.73e-05-1.13-1.141NEODyS: "Based on 553 optical observations (of which 4 are rejected as outliers) from 2013-10-08.856 to 2013-11-02.083."

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale

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.
