Traffic Report  on 6 November '13

Five objects reported inside ten LD

Five asteroids are reported to be within ten lunar distances (LD) of Earth today. 2013 VG2 is outbound from 3.90 to 6.33 LD while 2013 UE1 is inbound from 8.44 to 7.69 LD and 2013 VH2 from 9.01 to 8.60 LD. Intruder 2013 UX2 exits ten LD, traveling from 9.70 to 10.55 LD, and radar target 2001 AV43 comes inside, moving from 10.54 to 9.81 LD.

Coming into the neighborhood next, 2011 JY1 arrives inside ten LD on November 11th and radar target 2013 NJ arrives on November 19th.

This report was generated at 1553 UTC with today's DOU MPEC having follow-up for 2013 UE1 and observation of 68216 2001 CV26 from April.



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 6 November '13

The MPC's NEO Confirmation Page has 39 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 39 objects listed. Of these, eighteen 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 6 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 VZ4JPL Sentry23592052-2113411.8e-06-4.94-5.460JPL: "Analysis based on 9 observations spanning 1.9571 days (2013-Nov-04.43691 to 2013-Nov-06.39406)." Diameter approximately 0.085 km. from mean, weighted H=23.0.
2013 VQ4NEODyS15522018-2110565.88e-09-6.03-6.70NEODyS: "Based on 7 optical observations (of which 0 are rejected as outliers) from 2013-11-04.432 to 2013-11-05.279."

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.
