The latest A/CC news is available via framed access, RSS news feed, or redirection. - Note: A/CC has a main Web site and also a backup site with its own duplicate RSS news feed.

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 10 May '12

No objects reported inside ten LD

No objects are reported passing within ten lunar distances (LD) of our planet today. Up next, 2010 KK37 arrives inside ten LD on May 15th. This report was generated at 1612 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.

Radar Astrometry on 10 May '12

Radar observation of two objects

The JPL Solar System Dynamics Group Radar Astrometry database has added or updated the following small-body radar observing work:
