NEOCP Activity  on 26 August '07

The MPC's NEO Confirmation Page has 5 listings: 3 new, 2 updated

When last checked at 1757 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had three new and two updated listings. Of these, four were "one nighters."

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 26 August '07

Summary Risk Table for Risk Assessments Updated Today   (last checks: JPL at 1755 and NEODyS at 1756 UTC)
See the CRT page for a list of all objects rated recently as risks.
Note that the time horizon for JPL is 100 years from today and for NEODyS is now usually the year 2090.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) risk pages.

Notes for Today's Latest Risk Assessments
2007 PV27JPL14272043-208283.2e-07-4.14-4.520JPL: "Analysis based on 41 observations spanning 11.348 days (2007-Aug-14.56587 to 2007-Aug-25.91343)." Diameter approximately 0.280 km. from mean, weighted H=20.4.
NEODyS14272043-2082144.42e-07-4.04-4.760NEODyS: "Based on 41 optical observations (of which 0 are rejected as outliers) from 2007/08/14.567 to 2007/08/25.914."

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 an 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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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" for more about this.
