NEOCP Activity  on 1 January '11

The MPC's NEO Confirmation Page has 5 listings: 5 new

When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had five new listings. Of these, four 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.
