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. To keep track of what's new each day, watch the Chronology section.
Traffic Report on 3 September '12
No objects reported inside ten LD
There are no objects reported traveling within ten lunar distances (LD) of Earth today. Up next, radar target 2012 QG42 arrives inside ten LD on September 11th and 2010 JK1 on November 22nd.
This report was generated at 1544 UTC with follow-up in today's DOU MPEC for 2012 QG42.
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 3 September '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, one was a "one nighter."
To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
