WELCOME to A/CC's prototype daily news publication designed to be the viewing end of a planned autonomous 24-hour news service. The new tools and this publication format are working well enough now to share with readers. It is expected that this approach will require less time to maintain than our previous news and small asteroid pages, which were retired on May 14th. There's still more development ahead and there probably will be some glitches along the way, but this is what's needed to keep up with the increasing pace of minor-object news. The CRT page will be maintained separately for a little while longer, until all of this is working smoothly. And the CRT and small-asteroid ephemerides will be kept going.

Impact Risk Monitoring  on 17 June '07

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2349 UTC)
Note that the time horizon for JPL is 100 years from today and for NEODyS is usually the year 2080.
For the latest official risk assessments, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) risk pages.

Notes for Today's Latest Risk Assessments
2007 LB15JPL18262022-2101585.7e-07-2.81-3.340JPL: "Analysis based on 21 observations spanning 3.0624 days (2007-Jun-13.3467 to 2007-Jun-16.4091)." Diameter approximately 0.599 km. from mean, weighted H=18.8.
NEODyS18262022-2080465.09e-07-2.79-3.190NEODyS: "Based on 21 optical observations (of which 0 are rejected as outliers) from 2007/06/13.347 to 2007/06/16.410."

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale

For a list of all risk-rated objects recently in view, see our ephemerides page.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from an 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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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" for more about all this.
