Traffic Report  on 16 November '13

Three objects reported inside ten LD

Three asteroids are reported to be less than ten lunar distances (LD) from our planet today. Within Earth's Hill sphere, radar target 2001 AV43 is inbound from 3.76 to 3.33 LD. Further out, 2011 JY1 leaves ten LD, traveling from 8.32 to 10.15 LD, and 2013 VK13 enters ten LD, passing from 11.50 to 9.98 LD.

Coming around next, radar target 2013 NJ arrives inside ten LD on November 19th.

This report was generated at 2114 UTC with the discovery of risk-listed and already departed 2013 VD17 (MPEC), which is calculated to have passed Earth at 1.45 LD on November 11th. Sometime after 0523 UTC this morning, the Minor Planet Center posted a DOU MPEC dated yesterday with a 2138 time stamp. It carries astrometry for 2013 VK13 and departed objects 2013 VP11, 2013 VO11, 2013 VK11, intruder 2013 VJ11, and risk listed 2013 VM5, as well as observation of 277475 2005 WK4 from August. (At last check JPL has not yet posted new orbit solutions for 2013 VM5, 2013 VK11, and 2013 VP11, which may or may not indicate they are unannounced targets under active radar observation.)



Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. Earth's Hill sphere (of gravitational influence) is estimated to extend out to around 3.89 LD. 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 16 November '13

The MPC's NEO Confirmation Page has 3 listings

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

New MPECs  on 16 November '13

Minor Planet Electronic Circulars

As of last check at 2358 UTC, there have been three MPECs posted today from the International Astronomical Union's Minor Planet Center in Cambridge, Massachusetts. No Daily Orbit Update DOU MPEC has been posted yet, so visit the MPC Status Page for possible explanation.

Impact Risk Monitoring  on 16 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 VD17JPL Sentry16282065-207521.5e-06-6.70-6.990JPL: "Analysis based on 17 observations spanning 1.1674 days (2013-Nov-14.24215 to 2013-Nov-15.40956)." Diameter approximately 0.015 km. from mean, weighted H=26.8.

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.
