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 25 July '13
One object reported inside ten LD
One object may be inside ten lunar distances (LD) of Earth today. 2006 BL8 is calculated with great uncertainty to be inbound from 9.7 to 9.3 LD*. Headed in our direction next, 2003 DZ15 arrives inside ten LD on July 28th.
This report was generated at 1429 UTC with follow-up in today's DOU MPEC for 2003 DZ15.
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. "LD*" indicates some passage uncertainty. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.
NEOCP Activity on 25 July '13
The MPC's NEO Confirmation Page has 18 listings
When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had eighteen objects listed. Of these, one was a "one nighter." So far The Tracking News has counted a total of nineteen 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.
