Traffic Report  on 20 November '17

Nine objects reported inside ten LD

Nine visitors are reported inside ten lunar distances (LD) of our home world today. Nearest is newly announced 2017 WB1, which comes its closest to Earth on this passage, reaching 1.98 LD at 1807 UTC.

Your first A/CC local flying rock traffic report was generated at 2040 UTC with the discovery of 2017 WB1 (MPEC, DOU), and with follow-up in today's DOU MPEC for four objects active in the above traffic table, and for eight departed objects: 2017 WT, 2017 VE2, 2017 VG1, 2017 VE2, 2017 VG1, 2017 VD, 2017 VC, 496817 1989 VB, and including risk-listed objects 2017 VJ and intruder 2017 VL2.

Reading:  This is a banner day for reference materials concerning interstellar object 1I/`Oumuamua (A/2017 U1) and speculation about its origins. The European Southern Observatory has a news item, "ESO Observations Show First Interstellar Asteroid is Like Nothing Seen Before," which goes with a preprint (PDF), "Discovery and Characterization of the First Known Interstellar Object" by Karen J. Meech, Robert Weryk, Marco Micheli and fourteen others. Gemini Observatory has posted a related news release about `Oumuamua's "oddness" and telling how they "dropped everything so we could quickly point the Gemini telescopes at this object immediately after its discovery." Over at arXiv.org, an unrelated preprint proposes that "the most probable candidate for the A/2017 U1 parent stellar habitat is a star UCAC4 535-065571 but GJ 876 cannot be completely ruled out."
        We are maintaining a fairly exhaustive list of such references on a links page, including all related MPECs, like the newest today reporting Magdalena Ridge's continuing pursuit. A tally of MPECs to date finds that 23 professional and amateur observing facilities all around the world have contributed their data to this community scientific effort, not yet including some observing work reported in the news or preprint papers.



Notes: Ten times the distance to the Moon (ten LD) has no astronomical importance but is a useful boundary for reporting about transient natural objects that approach our planet's gravitational sphere of influence (SOI), which has a radius of about 2.41 LD from Earth's center. This puts a focus on some of the most important and very best NEO observation work, representative of the much larger NEO discovery and tracking effort. Object distances are derived by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.

NEOCP Activity  on 20 November '17

The MPC's NEO Confirmation Page has 85 listings

When last checked at 2330 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 85 objects listed. Of these, 41 were "one nighters." So far The Tracking News has counted a total of 110 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 20 November '17

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS at 2330 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 is 100 years from today and for NEODyS is usually the year 2090. Both also post impact solutions beyond 100 years for a few special objects.
For the latest official risk assessments, and for explanations of the terminology, see the NASA/JPL Sentry and NEODyS CLOMON2 risk pages.

2006 WY3JPL Sentry1731R E M O V E DJPL: Risk listing removed at 1102 UTC Nov. 25th

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.
