NEOCP Activity  on 23 March '08

The MPC's NEO Confirmation Page has 2 listings: 2 updated

When last checked at 2353 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had two updated listings. Of these, one was a "one nighter." So far The Tracking News has counted a total of four 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.
