NEOCP Activity  on 9 July '10

The MPC's NEO Confirmation Page has 10 listings: 3 new, 7 updated

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had three new and seven updated listings. Of these, two were "one nighters."

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 July '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.





Notes for Today's Latest Risk Assessments
2010 NHJPL Sentry19062077-210741.8e-06-6.25-6.550JPL: "Analysis based on 36 observations spanning 4.5851 days (2010-Jul-04.42235 to 2010-Jul-09.007465)." Diameter approximately 0.026 km. from mean, weighted H=25.6.
NEODyS1320207717.11e-07-6.58-6.580NEODyS: "Based on 36 optical observations (of which 0 are rejected as outliers) from 2010/07/04.423 to 2010/07/09.008."
2010 MZ112NEODyS13202029-2088527.12e-07-5.95-6.660NEODyS: "Based on 7 optical observations (of which 0 are rejected as outliers) from 2010/06/23.957 to 2010/06/24.684."
2010 MY112NEODyS13202014-2080431.98e-08-4.93-5.530NEODyS: "Based on 16 optical observations (of which 0 are rejected as outliers) from 2010/06/23.745 to 2010/06/25.134."

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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