WISE has its second asteroid discovery -- 2009 AG79 announced below. In this earlier infrared imagery, first discovery 2010 AB78 shows red against background stars. Queried about whether this was the first asteroidal object discovered from space, Gareth Williams at the IAU Minor Planet Center noted to A/CC that that milestone belongs to WISE's predecessor IRAS, which discovered Main Belter 3728 IRAS (1983 QF) and NEO 3200 Phaeton (1983 TB) a quarter century ago.

NEOCP Activity  on 28 January '10

The MPC's NEO Confirmation Page has 3 listings: 2 new, 1 updated

When last checked at 2310 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had two new and one updated listings. Of these, two were "one nighters." So far The Tracking News has counted a total of four 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.
