Lightcurves for nine asteroids were obtained at the Palmer Divide Observatory (PDO) in 2013 February and March. These represent the final objects out of more than 1100 lightcurves measured at PDO over fourteen years. Of the nine objects reported here, six were Hungaria members, two were NEAs, and the remaining two were main belt members. Analysis of the data resulted in a revised rotation period for the Hungaria member 4531 Asaro. The near-Earth asteroid (5828) 1991 AM was found to be a possible binary system with an unusual lightcurve for the secondary period, while follow-up on known Hungaria binary 5899 Jedicke lead to a revised period for the primary and confirmation of the orbital period of the satellite.
2013年2月和3月，在帕尔默分水岭天文台（PDO）获得了9颗小行星的光变曲线。这些是在14年里于PDO测量的1100多条光变曲线中的最后一批目标。在这里报告的9个天体中，6个是匈牙利族成员，2个是近地小行星，其余2个是主带成员。对数据的分析得出了匈牙利族成员4531阿萨罗的修正自转周期。近地小行星（5828）1991 AM被发现可能是一个双星系统，其次级周期的光变曲线异常，而对已知的匈牙利族双星5899杰迪切克的后续观测得出了主星的修正周期，并确认了卫星的轨道周期。
