Impact Risk Monitoring on 19 August '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. 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 (backup) risk pages.

2010 PR66	JPL Sentry	1500	2015-2109	26	3.9e-07	-3.75	-4.45	0	JPL: "Analysis based on 47 observations spanning 1.8847 days (2010-Aug-15.2648 to 2010-Aug-17.14952)." Diameter approximately 0.440 km. from mean, weighted H=19.4.
2010 PR66	NEODyS	1500	2015-2089	7	3.23e-08	-4.82	-4.89	0	NEODyS: "Based on 47 optical observations (of which 0 are rejected as outliers) from 2010/08/15.266 to 2010/08/17.150."

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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