Magdalena Ridge Observatory (MRO) in central New Mexico on Nov. 8th. This facility's fast-slewing 2.4-meter telescope (fast enough to track low-orbit satellites and nearby rocket launches) recently "moved from construction phase to operational phase" and is now "open for business." Its near-Earth object discovery follow-up work received NASA funding earlier this year. Photo by BA/Columbine.

NEOCP Activity  on 10 November '08

The MPC's NEO Confirmation Page has 6 listings: 3 new, 3 updated

When last checked at 2358 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had three new and three updated listings. Of these, five were "one nighters." So far The Tracking News has counted a total of eleven objects listed on the NEOCP at some point today.

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 10 November '08

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2358 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.
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.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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