NEOCP Activity on 31 August '09
The MPC's NEO Confirmation Page has 2 listings: 2 updated
When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had two updated listings. Of these, one 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.
