NEOCP Activity  on 31 August '20

The MPC's NEO Confirmation Page has 31 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 31 objects listed. Of these, 22 were "one nighters." So far The Tracking News has counted a total of 33 listings on the NEOCP today.

Impact Risk Monitoring  on 31 August '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
2016 NL56JPL Sentry18062023-21182597.179225e-07-3.59-4.350JPL: Computed at 20:13 March 5th of 2018 Pacific time based on 6 observations spanning 2.7820 days (2016-Jul-12.443828 to 2016-Jul-15.225848). Diameter approximately 0.265 km. from weighted mean H=20.61.

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale (next 100 years)

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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