NEOCP Activity on 12 July '10
The MPC's NEO Confirmation Page has 6 listings: 3 new, 3 updated
When last checked at 1435 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had three new and three updated listings. Of these, two were "one nighters."

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant 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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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" to learn more.
