NEOCP Activity  on 14 February '08

The MPC's NEO Confirmation Page has 11 listings: 4 new, 7 updated

When last checked at 2355 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had four new and seven updated listings. Of these, eight were "one nighters." So far The Tracking News has counted a total of 25 objects listed on the NEOCP at some point today.

Impact Risk Monitoring  on 14 February '08

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 recently as risks and our ephemerides page for a list of objects under current observation.
Note that the time horizon for JPL is 100 years from today and for NEODyS is 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.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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