Traffic Report  on 2 December '12

One object reported inside ten LD

One object is reported moving inside ten lunar distances (LD) from Earth today. 2012 WH1 leaves ten LD, passing from 8.97 to 10.04 LD.

On approach to arrive inside ten LD on December 7th, returning 2009 BS5 will be a very difficult recovery.

This report was generated at 1758 UTC with follow-up in today's DOU MPEC for 2012 WH1 and departed radar target 2010 JK1.


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 2 December '12

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. Of these, three 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.
