Asteroid Lightcurve Analysis at the Palmer Divide Observatory: 2010 December- 2011 March

Lightcurves for 34 asteroids were obtained at the Palmer Divide Observatory (PDO) from 2010 December through 2011 March: 434 Hungaria, 1019 Strackea, 2035 Stearns, 2047 Smetana, 3266 Bernardus, 3447 Burckhalter, 3511 Tsvetaeva, 4490 Bambery, 6384 Kervin, 6493 Cathybennett, 7187 Isobe, (7579) 1990 TN1, 7781 Townsend, (10779) 1991 LW, (12265) 1990 FG, (13578) 1993 MK, 13822 Stevedodson, (16562) 1992 AV1, (19131) 1988 CY3, (20936) 4835 T-1, (21056) 1991 CA1, (22696) 1998 QT105, (23336) 2579 P-L, (42612) 1998 EL3, (46784) 1998 HK117, (46803) 1998 KL33, (48470) 1991 TC2, (61461) 2000 QA31, (65739) 1993 SG13, (89550) 2001 XU97, (101771) 1999 FB58, (113567) 2002 TV36, 2001 GU8, and 2006 WH2. Previous results by the author for 7187 Isobe and (13578) 1993 MK are reviewed. The data obtained in 2010-11 for 3447 Burckhalter reveal that it is a "tumbler" (non-principal axis rotation), which explains previous, apparently contradictory results.
