NEOCP Activity on 28 May '10
The MPC's NEO Confirmation Page has 10 listings: 8 new, 2 updated
When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had eight new and two updated listings. Of these, three were "one nighters."
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 28 May '10
Notes for Today's Latest Risk Assessments
|2010 AU118||NEODyS||1502||2012-2086||10||5.35e-09||-3.91||-4.36||0||NEODyS: "Based on 19 optical observations (of which 0 are rejected as outliers) from 2010/01/13.896 to 2010/01/15.285."|
|2010 AR85||NEODyS||1502||2012-2090||95||5.82e-08||-2.55||-3.38||0||NEODyS: "Based on 12 optical observations (of which 0 are rejected as outliers) from 2010/01/07.862 to 2010/01/09.582."|
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
