NEOCP Activity  on 7 August '07

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

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

To learn how observers use the NEOCP, see Suno Observatory's Practical guide on how to observe NEOCP object.

Impact Risk Monitoring  on 7 August '07

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2355 UTC)
See the CRT page for a list of all objects rated as risks in the last month.
Note that the time horizon for JPL is 100 years from today and for NEODyS is usually the year 2080.
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
2004 XN44JPL1455R E M O V E DJPL: Risk listing removed at 1006 UTC.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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