Circulars:  MPEC 2006-U14

Notes:  2006 UR was discovered on 17 Oct. 2006 with the Spacewatch 0.9m telescope and announced the next day, which is when JPL posted it as an impact risk. During 20-21 Oct. JPL removed it as a risk.

Packed designation:  K06U00R

Current assessment:  NO impact solutions

Diameter:  145 meters (JPL 21 Oct. 2006 estimate)

Circulars:  MPEC 2006-U39

Notes:  2006 UQ17 was discovered on 19 Oct. 2006 by NEAT with its Mt. Palomar telescope and was announced on the 21st. It was posted that day by JPL as an impact risk and removed the next day.

The DOU MPEC of 26 Oct. reported prediscovery observations of 2006 UQ17 from the Catalina Sky Survey on 16 Oct, and the DOU MPEC of 3 Nov. published prediscovery observations from the Spacewatch 0.9m telescope on 28 Sept. and 2 Oct. and from NEAT/Palomar itself on 12 Oct. This object passed Earth at about 11.3 lunar distances on 2 Jan. 2007 and soon after that the calculation of its absolute magnitude (brightness) shrunk past H=22.0, to a roughly-estimated diameter of perhaps 135 meters.

Packed designation:  K06U17Q
