Traffic Report  on 25 February '13

One object reported inside ten LD

One asteroid is reported to be flying within ten lunar distances (LD) of Earth today. 2013 DS9 is outbound from 8.66 to 8.83 LD. Next known to come within ten LD is risk-listed 2007 EO88, which arrives inside on March 15th.

This report was generated at 1552 UTC with follow-up in today's DOU MPEC for departed 2013 DC1 and 2013 DB, and distant 68216 2001 CV26.

Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. Object distances are interpreted by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.

NEOCP Activity  on 25 February '13

The MPC's NEO Confirmation Page has 1 listing

When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had one object listed. This was a "one nighter." So far The Tracking News has counted a total of three listings on the NEOCP 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.
