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 28 February '13
One object reported inside ten LD
One asteroid is reported traveling within ten lunar distances (LD) of Earth today. 2013 DS9 exits ten LD, traveling from 9.93 to 10.79 LD. The next object known to be approaching is risk-listed radar target 2007 EO88, which arrives inside ten LD on March 15th.
This report was generated at 1442 UTC with observation of distant 68216 2001 CV26 reported in today's DOU MPEC.
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 28 February '13
The MPC's NEO Confirmation Page has 1 listing
When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had one object listed.
To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
