NEOCP Activity  on 23 December '07

The MPC's NEO Confirmation Page has 2 listings: 1 new, 1 updated

When last checked at 2237 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had one new and one updated listing. Both of these were "one nighters."

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