Contents  on 30 September '07

• IAU Minor Planet Center
  • NEOCP Activity -- five listings: 1 new, 4 updated
  • New MPECs -- one MPEC
  • Observers -- eight observing facilities
• Impact Risk Monitoring -- two objects reported
• Chronology

Resources:

• Consolidated Risk Tables - CRT page
• Ephemerides for risk-rated objects

Notes: Due to travel, these pages will update irregularly for the rest of the month.
Until September 16th this daily news page, which had included links to news and 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 30 September '07

The MPC's NEO Confirmation Page has 5 listings: 1 new, 4 updated

When last checked at 2304 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had one new and four updated listings. Of these, one was a "one nighter."

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 30 September '07

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
