Asteroid/Comet Connection (A/CC) Resources:
- Consolidated Risk Tables - the CRT page (archive)
Of 446 risk-listed objects, 14 have had news in the last 31 days. Updated at 1504 UTC on 15 June.
- Ephemerides for risk-rated & nearby objects + potential mission destinations
- News image catalog
- News old archive & Small Objects Archive
- Object Links - mainly for radar targets & close passers - updated 15 June 3x

The latest A/CC news is available via framed access, 
RSS news feed, or redirection. - Note: A/CC has a main Web site and also a backup site with its own duplicate RSS news feed.
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 15 June '12
One object reported inside ten LD
There is one object reported traveling inside ten lunar distances (LD) of Earth today. 2012 LT is outbound from 8.31 to 9.80 LD. 2012 LU arrives inside ten LD tomorrow and nothing else is known to approach as close until November.
This report was generated at 1505 UTC with follow-up in today's DOU MPEC for 2012 LU, 2012 LT, and 2012 LA.
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.

Impact Risk Monitoring on 15 June '12

| 2012 LR1 | JPL Sentry | 1504 | 2034-2106 | 7 | 3.7e-07 | -4.01 | -4.18 | 0 | JPL: "Analysis based on 56 observations spanning 5.5598 days (2012-Jun-09.40456 to 2012-Jun-14.96431)." Diameter approximately 0.270 km. from mean, weighted H=20.5. |

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale
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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
