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 May '13
Two objects reported inside ten LD
Our only remaining visitors less than ten lunar distances (LD) from Earth both depart from the reporting "bubble" today. 2013 KT1 passes from 8.90 to 10.12 LD and 2013 KB travels from 9.23 to 10.65 LD. Next known to come this close is 2009 FE, which arrives inside ten LD on June 2nd.
This report was generated at 1354 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 28 May '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.

Impact Risk Monitoring on 28 May '13
At last check (NEODyS and JPL at 2359 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.
