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 May '13
Four objects reported inside ten LD
There are four asteroids reported passing within ten lunar distances (LD) of Earth today. 2013 KB is outbound from 5.22 to 6.48 LD, 2013 KT1 from 5.45 to 6.54 LD, 2013 KS1 from 7.19 to 8.90 LD, and 2013 KA from 8.83 to 9.95 LD.
On approach next, 2009 FE arrives inside ten LD on June 2nd.
This report was generated at 1300 UTC with today's DOU MPEC carrying observation of 2013 KQ1 from last week.
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 25 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.
