Traffic Report  on 31 July '12

No objects reported inside ten LD

No objects are reported moving inside ten lunar distances (LD) of Earth today and none are known to be coming in until November.

This report was generated at 1437 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.
