Traffic Report  on 31 March '13

Two objects reported inside ten LD

Two objects are reported to be within ten lunar distances (LD) of our planet today. Radar target 2013 FB8 is outbound from 4.26 to 4.83 LD and risk-listed 2013 EL89 from 5.06 to 6.16 LD.

Next known to be coming around is risk-listed 2010 GM23, which arrives inside ten LD on April 10th.

This report was generated at 1551 UTC with follow-up in today's DOU MPEC for 2013 FB8 and departed 2013 FD8 (adding 5.838 days to a 4.722-day observing arc), and observation of 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 31 March '13

The MPC's NEO Confirmation Page has 3 listings

When last checked at 2359 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had three objects listed. Of these, two were "one nighters."

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