NEOCP Activity  on 19 August '07

The MPC's NEO Confirmation Page has 1 listing: 1 new

When last checked at 2354 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had one new listing. This was a "one nighter."

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 19 August '07

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2354 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 PV27JPL14272031-2105181.7e-06-3.33-3.830JPL: "Analysis based on 31 observations spanning 3.9467 days (2007-Aug-14.56587 to 2007-Aug-18.51255)." Diameter approximately 0.280 km. from mean, weighted H=20.4.
NEODyS14272031-2082241.41e-06-3.38-3.820NEODyS: "Based on 31 optical observations (of which 0 are rejected as outliers) from 2007/08/14.567 to 2007/08/18.513."

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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