Notes: Until September 16th this daily news page, which had included links to news and to science papers as well as some occasional original reporting, was called Major News About Minor Objects. Without the news-link and science-link sections, this page was renamed as The Tracking News to more accurately reflect its continuing purpose.

The latest news: framed access (best), RSS news feed (flags updates), or redirection - Note: A/CC has a main Web site and a backup site.

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 this year 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 9 October '07

The MPC's NEO Confirmation Page has 17 listings: 10 new, 7 updated

When last checked at 2355 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had ten new and seven updated listings. Of these, fifteen were "one nighters." So far Tracking News has counted a total of 34 objects listed on the NEOCP at some point today.

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

Impact Risk Monitoring  on 9 October '07

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2355 UTC)
See the CRT page for a list of all objects rated recently as risks.
Note that the time horizon for JPL is 100 years from today and for NEODyS is now usually the year 2090.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) risk pages.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from an orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" for more about this.
