Traffic Report  on 14 May '13

No objects reported inside ten LD

There are presently no objects reported within a radius of ten lunar distances (LD) from Earth, but risk-listed 2013 JM22 arrives inside ten LD tomorrow. And 2009 FE comes inside on June 2nd.

This report was generated at 1303 UTC with follow-up in today's DOU MPEC for 2013 JF1.



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 14 May '13

The MPC's NEO Confirmation Page has 42 listings

When last checked at 2325 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 42 objects listed. Of these, nine were "one nighters." So far The Tracking News has counted a total of 51 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 14 May '13

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2325 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 JM22NEODyS12582073-209541.05e-06-4.66-4.860NEODyS: "Based on 32 optical observations (of which 1 are rejected as outliers) from 2013-05-12.346 to 2013-05-13.371."
2013 JW17JPL Sentry1258R E M O V E DJPL: Risk listing removed at 0949 UTC.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
