NEOCP Activity  on 15 June '08

The MPC's NEO Confirmation Page has 4 listings: 3 new, 1 updated

When last checked at 2357 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had three new and one updated listings. All of these were "one nighters." So far The Tracking News has counted a total of eight 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.
