No Vulcanoids yet, the Messenger mission reported yesterday. The spacecraft, which launched six years ago and goes into orbit around Mercury next March, has been engaged in a multi-perihelion campaign to find a theoretical population of asteroids between Mercury and the Sun. See more info here. This May 6th image of the Earth-Moon system comes from that search. Credit NASA/JHUAL/CIW (NASA, Johns Hopkins Univ. Applied Physics Laboratory, and Carnegie Inst. of Washington).

NEOCP Activity on 18 August '10
The MPC's NEO Confirmation Page has 1 listing: 1 new
When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had one new listing. This was a "one nighter." So far The Tracking News has counted a total of five listings on the NEOCP at some point 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.

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
