NEOCP Activity on 3 July '10
The MPC's NEO Confirmation Page has 10 listings: 6 new, 4 updated
When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had six new and four updated listings. Of these, one was a "one nighter." So far The Tracking News has counted a total of twelve 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.
