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 23 July '13
No objects reported inside ten LD
There are no objects reported traveling inside ten lunar distances (LD) of our planet today. Approaching our neighborhood next, 2006 BL8 may arrive inside ten LD tomorrow (uncertainty +/- two days), and 2003 DZ15 arrives on July 28th.
This report was generated at 1349 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 July '13
The MPC's NEO Confirmation Page has 16 listings
When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had sixteen objects listed. Of these, three were "one nighters."
To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
