NEOCP Activity on 9 June '10
The MPC's NEO Confirmation Page has 8 listings: 5 new, 3 updated
When last checked at 2303 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had five new and three updated listings. Of these, three were "one nighters." So far The Tracking News has counted a total of nineteen listings on the NEOCP at some point today.
To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.

Impact Risk Monitoring on 9 June '10
Notes for Today's Latest Risk Assessments
|2010 KH||JPL Sentry||2303||2018-2077||29||1.4e-08||-4.59||-5.11||0||JPL: "Analysis based on 21 observations spanning 3.3738 days (2010-May-16.17098 to 2010-May-19.5448)." Diameter approximately 0.593 km. from mean, weighted H=18.8.|
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
