Traffic Report  on 30 July '12

No objects reported inside ten LD

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

This report was generated at 0331 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.
