Traffic Report  on 27 November '12

Three objects reported inside ten LD

Three objects are reported passing inside ten lunar distances (LD) of our planet today. Risk-listed 2012 WR10 is outbound from 7.24 to 7.90 LD and radar target 2010 JK1 from 9.38 to 9.67 LD, and 2012 WH1 is inbound from 8.79 to 8.04 LD.

Coming toward us next, 2009 BS5 arrives inside ten LD on December 7th.

This report was generated at 1658 UTC with follow-up in today's DOU MPEC for 2012 WR10, 2012 WH1, 2010 JK1, and departed 2012 WR3.


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 27 November '12

The MPC's NEO Confirmation Page has 6 listings

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

Impact Risk Monitoring  on 27 November '12

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS at 2359 and JPL at 2358 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
2012 WR10JPL Sentry1644208316.4e-09-10.26-10.30JPL: "Analysis based on 30 observations spanning 4.3117 days (2012-Nov-22.21759 to 2012-Nov-26.529251)." Diameter approximately 0.007 km. from mean, weighted H=28.5.
NEODyS16442093-209443.01e-07-8.64-8.680NEODyS: "Based on 30 optical observations (of which 1 are rejected as outliers) from 2012-11-22.218 to 2012-11-26.530."

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.
