Radar Astrometry on 18 June '20

Radar observation of four objects

The JPL Solar System Dynamics Group Radar Astrometry database has added or updated the following small-body radar observing work:

Data update noted at 2110 UTC when the database was dated 18 June

2020 HB6 (close passer, NHATS target) from Arecibo (May 6.17 velocity) - NHATS
2016 HP6 (close passer, NHATS target) from Arecibo (May 6.23 velocity & 6.24 range) - NHATS

Data update noted at 2204 UTC when the database was dated 18 June

2020 HC6 (close passer, NHATS target) from Arecibo (May 7.02 velocity & 7.04 range) - NHATS
438908 2009 XO from Arecibo (May 3.82 velocity, 3.85 range, 3.90 range & 7.00 range)

Photometry and some astrometry is needed for upcoming radar targets. See Arecibo and Goldstone schedules.

NEOCP Activity on 18 June '20

The MPC's NEO Confirmation Page has 62 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 62 objects listed. Of these, 27 were "one nighters." So far The Tracking News has counted a total of 80 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 18 June '20

**Summary Risk Table for Risk Assessments Updated Today** (last checks: NEODyS at 2359 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.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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