NEOCP Activity on 19 January '10
The MPC's NEO Confirmation Page has 5 listings: 2 new, 3 updated
When last checked at 2301 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had two new and three updated listings. Of these, three were "one nighters." So far The Tracking News has counted a total of eight 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.
