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 27 May '13
Two objects reported inside ten LD
Two asteroids are reported to be within ten lunar distances (LD) of our planet today. 2013 KT1 is outbound from 7.70 to 8.90 LD and 2013 KB from 7.83 to 9.23 LD. Approaching our neighborhood next, 2009 FE arrives inside ten LD on June 2nd.
This report was generated at 1417 UTC with observation in today's DOU MPEC of 2013 KT1 and 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 27 May '13
The MPC's NEO Confirmation Page has 1 listing
When last checked at 1900 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had one object listed.
To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.

Impact Risk Monitoring on 27 May '13
Notes for Today's Latest Risk Assessments
|2013 JA17||JPL Sentry||1900||2054-2111||6||3.8e-09||-5.69||-6.09||0||JPL: "Analysis based on 13 observations spanning 3.9520 days (2013-May-08.43448 to 2013-May-12.38647)." Diameter approximately 0.518 km. from mean, weighted H=19.1.|
An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" to learn more.
