NEOCP Activity on 8 January '09
The MPC's NEO Confirmation Page has 2 listings: 1 new, 1 updated
When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had one new and one updated listing. Of these, one was a "one nighter." So far The Tracking News has counted a total of six objects listed on the NEOCP at some point today.
To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object by Birtwhistle et al. at Suno Observatory.
