* * * * * Near Earth Asteroids * * * * *

In this section we report visual observations of unusual asteroids, that we find of particular interest. The first group consists of NEA's (Near Earth Asteroids), mainly Apollo-, Amor- and Aten-type objects, and the second group consists of asteroidal objects in cometary orbits. Observed objects since August 2000: * Apollo-type asteroids. 2000 UG11 (138877) = 2000 XG47 2001 YB5 2002 NY40 (22771) = 1999 CU3 69230 Hermes 2004 JP1 4179 Toutatis 2004 RZ164 3200 Phaethon (100085) = 1992 UY4 (363790) = 2005 JE46 1862 Apollo (23187) = 2000 PN9 2004 XP14 (11405) = 1999 CV3 (374851) = 2006 VV2 2007 TU24 4450 Pan 2009 DO111 2010 JL33 2012 QG42 (357439) = 2004 BL68 1566 Icarus (164121) = 2003 YT1 5143 Heracles (143404) = 2003 BD44 2014 JO25 (276033) = 2002 AJ129 1981 Midas 2010 WC9 * Aten-type asteroids. 2001 CP36 (66391) = 1999 KW4 (33342) = 1998 WT24 2100 Ra-Shalom (66146) = 1998 TU3 (341843) = 2008 EV5 367943 Duende = 2012 DA14 * Amor-type asteroids.

It appears that this is a 'double asteroid'. The following information was extracted from IAUC 7518: Arecibo radar delay-Doppler images [2380 MHz, 12.6 cm] obtained on Nov. 3-7 show that 2000 UG11 is a binary system. Preliminary estimates of average diameters, based on range extents at 15-m resolution, are 230 and 100 m. Goldstone radar observations [8560 MHz, 3.5 cm] on Nov. 6 confirm the binary nature of this minor planet. Using the combined data sets, we derive an orbital period of 19 +/- 1.5 hr.)
