NEOCP Activity  on 3 September '20

The MPC's NEO Confirmation Page has 20 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 20 objects listed. Of these, ten were "one nighters." So far The Tracking News has counted a total of 26 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 3 September '20

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS 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 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
2020 PG6JPL Sentry1700R E M O V E DJPL: Risk listing removed at 1605 UTC today
NEODyS17002034-204853.41e-09-9.03-9.070NEODyS: "Based on 30 optical observations (of which 0 are rejected as outliers) from 2020-08-11.368 to 2020-09-02.136."
2012 WR10JPL Sentry17002087-209627.738e-07-8.19-8.400JPL: Computed at 07:03 April 7th of 2017 Pacific time based on 45 observations spanning 26.156 days (2012-Nov-22.21759 to 2012-Dec-18.37324). Diameter approximately 0.007 km. from weighted mean H=28.52.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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