Navigation tips: Use the << and >> arrows on the menus for each regular section (Observers, Risks, etc.) to move to the previous and next day's news for that section. Use the Index menu item to access specific days through a calendar interface. And use the all-up news archive to access news from any time since A/CC began in early 2002.

Traffic Report on 1 December '12
Two objects reported inside ten LD
Two objects are reported to be within ten lunar distances (LD) of our planet today. 2012 WH1 is outbound from 8.16 to 8.97 LD and risk-listed 2012 WR10 departs from inside ten LD, traveling from 9.93 to 10.62 LD.
The next known visitor, 2009 BS5, arrives inside ten LD on December 7th.
This report was generated at 1826 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 1 December '12
The MPC's NEO Confirmation Page has 4 listings
When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had four 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.
