NEOCP Activity  on 9 February '10

The MPC's NEO Confirmation Page has 16 listings: 8 new, 8 updated

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had eight new and eight updated listings. Of these, eleven were "one nighters." So far The Tracking News has counted a total of 20 listings on the NEOCP at some point today.

To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.

Impact Risk Monitoring  on 9 February '10

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.
The time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090. Beginning Jan. 22nd, both are also posting impact solutions beyond 100 years for a few objects.
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
2010 CAJPL Sentry15482019-202844.5e-05-3.46-3.470JPL: "Analysis based on 28 observations spanning 2.9758 days (2010-Feb-05.19638 to 2010-Feb-08.172148)." Diameter approximately 0.041 km. from mean, weighted H=24.6.
NEODyS15482019-206364.65e-05-3.45-3.460NEODyS: "Based on 28 optical observations (of which 0 are rejected as outliers) from 2010/02/05.197 to 2010/02/08.173."

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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