NEOCP Activity  on 26 August '11

The MPC's NEO Confirmation Page has 18 listings

When last checked at 2336 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had eighteen objects listed. Of these, eight were "one nighters." So far The Tracking News has counted a total of 39 listings on the NEOCP today.

Impact Risk Monitoring  on 26 August '11

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2345 UTC)
See the CRT page for a list of all objects rated recently as risks and our ephemerides page for a list of risk-listed objects under current observation.
The time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090. Both also post impact solutions beyond 100 years for a few special objects.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON risk pages.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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