NEOCP Activity on 9 March '08

The MPC's NEO Confirmation Page has 18 listings: 2 new, 16 updated

When last checked at 2354 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had two new and sixteen updated listings. Of these, seven were "one nighters." So far The Tracking News has counted a total of 20 objects listed on the NEOCP at some point today.

To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object by Birtwhistle et al. at Suno Observatory.

MPEC 2008-E72 - "19:02 UT" - 2008 ED8

K08E08D 2008 ED8 (risk-listed, Earth MOID=1.3 LD, H=24.3 ~47m) was discovered at 0401 UT on 8 March by LINEAR, which observed it at March 8.17-21p5. The discovery was confirmed by KLENOT (March 8.83p5), Klet Obs. (March 8.86-87p7), CEAMIG-REA (March 9.00p5), Astronomical Research Obs. (ARO) (March 9.08-09p6), the Mt.

(March 9.34-35p7 & 9.39-40p8), the Siding Spring Survey (SSS) (March 9.50p9), and Cristovao Jacques via RAS Obs. Moorook (March 9.54p5). This object is now within ten lunar distances (LD) of Earth, reaching 1.5 LD on 10 March.

Impact Risk Monitoring on 9 March '08

**Summary Risk Table for Risk Assessments Updated Today** (last checks: NEODyS and JPL at 2355 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.
Note that the time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) 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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
