NEOCP Activity  on 8 July '20

The MPC's NEO Confirmation Page has 15 listings

When last checked at 2314 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had fifteen objects listed. Of these, two were "one nighters." So far The Tracking News has counted a total of seventeen listings on the NEOCP today.

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 8 July '20

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS at 2314 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.

Notes for Today's Latest Risk Assessments
2019 NF7JPL Sentry18002072-208029.55937e-06-6.66-6.670JPL: Computed at 09:27 July 18th of 2019 Pacific time based on 14 observations spanning 1.2364 days (2019-Jul-09.237408 to 2019-Jul-10.473823). Diameter approximately 0.008 km. from weighted mean H=28.10.
2018 NWJPL Sentry18002046-2117670.0003416024045-4.77-5.370JPL: Computed at 07:28 July 11th of 2018 Pacific time based on 19 observations spanning 2.0151 days (2018-Jul-08.34866 to 2018-Jul-10.363716). Diameter approximately 0.009 km. from weighted mean H=27.83.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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