First observations from the WISE infrared space telescope were reported yesterday with its January 12th discovery of asteroid 2010 AB78. Due to fixed pointing from polar orbit along Earth's day-night terminator, immediate ground-based confirmation of coming WISE discoveries will be critical.

Impact Risk Monitoring  on 23 January '10

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2310 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.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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