Lightcurves for 41 asteroids were obtained at the Palmer Divide Observatory (PDO) from 2013 January through March: 785 Zwetana, 1509 Esclangona, 1599 Giomus, 1925 Franklin-Adams, 2048 Dwornik, 2491 Tvashtri, 3007 Reaves, 3720 Hokkaido, 4719 Burnaby, 4736 Johnwood, 5841 Stone, (6394) 1990 QM2, (8825) 1988 MF, 9231 Shimaken, 9387 Tweedledee, (11405) 1999 CV3, 11437 Cardalda, 16669 Rionuevo, (18486) 1996 AS2, (27713) 1989 AA, 28126 Nydegger, (29242) 1992 HB4, (29298) 1993 SA14, (29308) 1993 UF1, (31354) 1998 TR3, (32750) 1981 EG9, (32772) 1986 JL, (35340) 1997 GV18, (41044) 1999 VW6, (56318) 1999 UR3, (66092) 1998 SD, (68537) 2001 VC123, (75648) 2000 AW59, (99008) 2001 DU52, (125738) 2001 XE116, (135486) 2001 XP2, (137199) 1999 KX4, (154347) 2002 XK4, (343098) 2009 DV42, (349068) 2006 YT13, and 2013 BE19. The 2013 results for 9387 Tweedledee lead to a revised analysis of the data from 2006 for that asteroid and resolved the ambiguous solution reported at that time.
2013年1月至3月期间，在帕尔默分水岭天文台（PDO）获取了41颗小行星的光变曲线，这些小行星分别是：785 Zwetana、1509 Esclangona、1599 Giomus、1925 Franklin - Adams、2048 Dwornik、2491 Tvashtri、3007 Reaves、3720 Hokkaido、4719 Burnaby、4736 Johnwood、5841 Stone、(6394) 1990 QM2、(8825) 1988 MF、9231 Shimaken、9387 Tweedledee、(11405) 1999 CV3、11437 Cardalda、16669 Rionuevo、(18486) 1996 AS2、(27713) 1989 AA、28126 Nydegger、(29242) 1992 HB4、(29298) 1993 SA14、(29308) 1993 UF1、(31354) 1998 TR3、(32750) 1981 EG9、(32772) 1986 JL、(35340) 1997 GV18、(41044) 1999 VW6、(56318) 1999 UR3、(66092) 1998 SD、(68537) 2001 VC123、(75648) 2000 AW59、(99008) 2001 DU52、(125738) 2001 XE116、(135486) 2001 XP2、(137199) 1999 KX4、(154347) 2002 XK4、(343098) 2009 DV42、(349068) 2006 YT13以及2013 BE19。9387 Tweedledee的2013年观测结果促使对该小行星2006年的数据进行了重新分析，并解决了当时报告的模糊结果。
