NEOCP Activity on 12 September '08
The MPC's NEO Confirmation Page has 2 listings: 2 new
When last checked at 2258 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had two new listings. Of these, one was a "one nighter."
To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object by Birtwhistle et al. at Suno Observatory.
