Navigation tips: Use the << and >> arrows on the menus for each regular section (Observers, Risks, etc.) to move to the previous and next day's news for that section. Use the Index menu item to access specific days through a calendar interface. And use the all-up news archive to access news from any time since A/CC began in early 2002. To keep track of what's new each day, watch the Chronology section.
Traffic Report on 25 January '13
One object reported inside ten LD
One object is reported to be within ten lunar distances (LD) of Earth today. 2013 BT15 is outbound from 7.75 to 9.05 LD.
Coming toward Earth next, 2013 BS45 arrives inside ten LD on January 30th, and 2013 BV15 and intruder 2012 DA14 (risk-listed radar target) come inside on February 8th.
This report was generated at 1639 UTC with today's DOU MPEC reporting observation of 2012 UT9 from 2.59 days before its discovery last October, adding to its previous 6.70-day observation arc.
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 25 January '13
The MPC's NEO Confirmation Page has 13 listings
When last checked at 2309 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had thirteen objects listed. Of these, seven were "one nighters." So far The Tracking News has counted a total of fourteen 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.
