Traffic Report  on 23 November '13

Two objects reported inside ten LD

Two objects are reported to be within ten lunar distances (LD) of Earth today. Radar target 2013 NJ is inbound from 5.38 to 4.08 LD and radar target 2001 AV43 is outbound from 4.43 to 5.05 LD. Next known to be coming inside ten LD is 2011 YD29, which arrives late next month.

This report was generated at 1631 UTC.



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 23 November '13

The MPC's NEO Confirmation Page has 5 listings

When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had five objects listed. All of these 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.
