NEOCP Activity  on 29 May '08

The MPC's NEO Confirmation Page has 9 listings: 3 new, 6 updated

When last checked at 2153 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had three new and six updated listings. All of these were "one nighters." So far The Tracking News has counted a total of twelve 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 29 May '08

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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