Traffic Report  on 19 July '12

No objects reported inside ten LD

No asteroids are reported flying within ten lunar distances (LD) of our planet today, but newly announced 2012 OQ arrives inside ten LD on July 22nd.

This report was updated at 1950 UTC with new discovery 2012 OQ (MPEC) and, earlier, follow-up in today's DOU MPEC for departed 1999 XL136. Today's first traffic report was generated at 1519 UTC.


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 19 July '12

The MPC's NEO Confirmation Page has 6 listings

To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
