Asteroid Lightcurve Analysis at the Palmer Divide Observatory: 2012 March - June

Lightcurves for 34 asteroids, including a new Hungaria binary, were obtained at the Palmer Divide Observatory (PDO) from 2012 March to July: 1656 Suomi, 3169 Ostro, 3266 Bernardus, 4116 Elachi, 4483 Petofi, 4490 Bambery, 5968 Trauger, 6107 Osterbrock, 6354 Vangelis, 6517 Buzzi, 6670 Wallach, 7087 Lewotsky, (11304) 1993 DJ, (17129) 1999 JM78, (17590) 1995 CG, (20996) 1986 PB, (23482) 1991 LV, (24702) 1991 OR, (31182) 1997 YZ3, (31881) 2000 FL15, (42811) 1999 JN81, (47143) 1999 LL31, (48307) 2002 LP53, (49674) 1999 SB5, (51302) 2000 KY54, (51381) 2001 BG51, (51386) 2001 CN35, (74081) 1998 OU1, (79472) 1998 AX4, (88259) 2001 HJ7, (326732) 2003 HB6, 2011 WV134, 2012 AA11, and 2012 DO. The Hungaria asteroid (79472) 1998 AX2 showed what appeared to be mutual events (occultations/eclipses) in its lightcurve, likely indicating a satellite. Analysis of the data gives an orbital period of 25.95 ± 0.02 h and size ratio of Ds/Dp ~ 0.32 ± 0.03.
