To keep track of what's new each day, watch the Chronology section.
NEOCP Activity on 5 February '10
The MPC's NEO Confirmation Page has 2 listings: 1 new, 1 updated
When last checked today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had one new and one updated listing. So far The Tracking News has counted a total of three 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.
