Impact Risk Monitoring  on 30 January '09

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2359 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 some objects with impact solutions beyond 100 years.
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
2009 BR5JPL Sentry14432059-207861.9e-06-4.16-4.230JPL: "Analysis based on 31 observations spanning 8.8918 days (2009-Jan-20.45513 to 2009-Jan-29.34697)." Diameter approximately 0.130 km. from mean, weighted H=22.1.
NEODyS14432059-208182.02e-06-4.13-4.220NEODyS: "Based on 31 optical observations (of which 0 are rejected as outliers) from 2009/01/20.456 to 2009/01/29.348."

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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