NEOCP Activity  on 30 December '10

The MPC's NEO Confirmation Page has 4 listings: 3 new, 1 updated

When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had three new and one updated listings. Of these, two were "one nighters." So far The Tracking News has counted a total of seven 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.
