NEOCP Activity on 1 July '08
The MPC's NEO Confirmation Page has 5 listings: 5 updated
When last checked at 2357 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had five updated listings. Of these, three were "one nighters." So far The Tracking News has counted a total of thirteen 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 1 July '08
Notes for Today's Latest Risk Assessments
|2008 MV1||JPL Sentry||1905||2026-2093||22||2.4e-07||-4.93||-5.41||0||JPL: "Analysis based on 11 observations spanning .93636 days (2008-Jun-30.66182 to 2008-Jul-01.59818)." Diameter approximately 0.140 km. from mean, weighted H=21.9.|
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
