No longer just a point of light, Main Belt asteroid 21 Lutetia today becomes the largest asteroid yet visited as the Rosetta mission flies past. For more info about flyby progress and resources, see the Rosetta blog.

Contents  on 10 July '10

• IAU Minor Planet Center
  • NEOCP Activity -- eight listings: 2 new, 6 updated
  • New MPECs -- four MPECs
• Observers -- nineteen observing facilities
• Impact Risk Monitoring -- nothing to report
• Chronology

Note: A/CC news pages will update infrequently for much of the remainder of July. (And our main Web site has been down and up this Saturday for reasons uknown. Be sure to bookmark our backup site -- see below.)

Resources:

• Consolidated Risk Tables - the CRT page
    Of 330 risk-listed objects, 29 have had news in the last month. Updated at 1436 UTC.
• Earth's Busy Neighborhood Traffic Report
    Two objects are known to be within ten LD of Earth today. Updated at 0204 UTC.
• Ephemerides for risk-rated and nearby objects
• News image catalog
• Old & new CRT Archive
• Old News Archive & Small Objects Archive

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.

NEOCP Activity  on 10 July '10

The MPC's NEO Confirmation Page has 8 listings: 2 new, 6 updated

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had two new and six updated listings. Of these, one was a "one nighter." So far The Tracking News has counted a total of ten listings on the NEOCP at some point today.

To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
