NEOCP Activity  on 16 January '10

The MPC's NEO Confirmation Page has 7 listings: 2 new, 5 updated

When last checked at 2338 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had two new and five updated listings. Of these, four were "one nighters." So far The Tracking News has counted a total of nine 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.
