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 24 February '13
Two objects reported inside ten LD
There are two visitors reported to be inside a radius of ten lunar distances (LD) from Earth today. 2013 DS9 comes its closest to Earth this time around, reaching 8.66 LD at 2145 UTC, and radar target 2013 BS45 exits from ten LD, passing from 9.53 to 10.14 LD.
Headed our way next, risk-listed 2007 EO88 arrives inside ten LD on March 15th.
This report was generated at 1656 UTC with follow-up in today's DOU MPEC for departed 2013 CZ87 and 2013 CE82 and distant 68216 2001 CV26.
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 24 February '13
The MPC's NEO Confirmation Page has 2 listings
When last checked at 2312 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had two objects 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.

Impact Risk Monitoring on 24 February '13
At last check (NEODyS and JPL at 2312 UTC) there was no risk monitoring news to report yet today, except that observation of one risk-listed object has been reported (see today's DOU MPEC above). Visit the CRT to view activity in the last four weeks and our ephemerides page for a complete list of risk-rated objects under current observation or having recent news.
