Traffic Report  on 8 April '17

Nine objects reported inside ten LD

Today nine minor planets are traversing an imaginary spherical space with a radius of ten lunar distances (LD) from our planet's center. Closest of these is NHATS target 2017 FT102, which moves away from 2.41 to 2.87 LD.

This report was generated at 1541 UTC. The International Astronomical Union Minor Planet Center in Cambridge, Massachusetts reports today that the DOU MPEC has been delayed by computer problems. No MPECs have been posted since late Thursday.

Notes: Ten times the distance to the Moon (ten LD) has no astronomical importance but is a useful boundary for reporting on transient natural objects that approach the actually significant 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 8 April '17

The MPC's NEO Confirmation Page has 73 listings

When last checked at 2357 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 73 objects listed. Of these, 26 were "one nighters." So far The Tracking News has counted a total of 74 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.

New MPECs  on 8 April '17

Minor Planet Electronic Circulars

As of last check at 2357 UTC, there have been no MPECs posted today from the International Astronomical Union's Minor Planet Center in Cambridge, Massachusetts.

When no Daily Orbit Update (DOU) MPEC has been posted by this time of day, visit the MPC Status Page for possible explanation.

Observers  on 8 April '17

Without MPECs with observations to report, we have no observers to list yet today. For a list of all participating observatories that have Web addresses, see A/CC's Observatory Links page.

Impact Risk Monitoring  on 8 April '17

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2357 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 JPL NEO Program Sentry and NEODyS CLOMON2 risk pages.

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.
