セロ・トロロ汎米天文台
In the 1980s, a rotational lightcurve of "Pandarus" was obtained from photometric observations by Linda French using the SMARTS 0.9-meter reflector at Cerro Tololo Inter-American Observatory in Chile. Lightcurve analysis gave a well-defined rotation period of 8.480 hours with a brightness variation of 0.58 magnitude (), indicative of a non-spheroidal shape.
