Traffic Report  on 8 June '12

One object reported inside ten LD

One asteroid is reported traveling within ten lunar distances (LD) of Earth today. 2012 LA is outbound from 8.85 to 9.08 LD. No other objects are known to be coming inside ten LD until November.

This report was generated at 1545 UTC with follow-up in today's DOU MPEC for 2012 LA, and was revised at 1625 UTC with new distance calculations.


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 8 June '12

The MPC's NEO Confirmation Page has 2 listings

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

New MPECs  on 8 June '12
