NEOCP Activity  on 30 June '20

The MPC's NEO Confirmation Page has 34 listings

When last checked at 2011 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 34 objects listed. Of these, nineteen were "one nighters." So far The Tracking News has counted a total of 40 listings on the NEOCP today.

Impact Risk Monitoring  on 30 June '20

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS at 2011 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 and NEODyS listings is 100 years, and both post impact solutions beyond that for some special objects.
For the latest official risk assessments, and for explanations of the terminology, see the NASA/JPL Sentry and NEODyS CLOMON2 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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
