Traffic Report  on 19 November '13

Three objects reported inside ten LD

There are three objects reported flying within ten lunar distances (LD) of our planet today. Inside Earth's Hill sphere, radar target 2001 AV43 is outbound from 2.96 to 3.09 LD. Further away, 2013 VK13 comes its closest to Earth this time around, reaching 8.08 LD at 1251 UT, and radar target 2013 NJ comes inside ten LD, passing from 11.20 to 9.70 LD.

Next known to be coming into the neighborhood is 2011 YD29 late next month.

This report was generated at 1716 UTC. No DOU MPEC has been issued yet today.



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 19 November '13

The MPC's NEO Confirmation Page has 9 listings

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

New MPECs  on 19 November '13

Minor Planet Electronic Circulars

As of last check at 2359 UTC, there have been no MPECs posted today from the International Astronomical Union's Minor Planet Center in Cambridge, Massachusetts.
