NEOCP Activity  on 13 May '20

The MPC's NEO Confirmation Page has 56 listings

Impact Risk Monitoring  on 13 May '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
2019 QE7JPL Sentry16302097-211981.701648e-06-6.92-7.290JPL: Computed at 06:34 today Pacific time based on 31 observations spanning 26.888 days (2019-Aug-31.57014 to 2019-Sep-27.457719). Diameter approximately 0.015 km. from weighted mean H=26.72.
NEODyS16302097-2116112.4e-06-6.75-7.070NEODyS: "Based on 31 optical observations (of which 0 are rejected as outliers) from 2019-08-31.571 to 2019-09-27.459."
2014 UX34JPL Sentry16302084-208414.119e-10-7.82-7.820JPL: Computed at 06:33 today Pacific time based on 62 observations spanning 36.925 days (2014-Oct-23.33075 to 2014-Nov-29.25596). Diameter approximately 0.120 km. from weighted mean H=22.32.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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