NEAR-EARTH ASTEROID LIGHTCURVE ANALYSIS AT THE CENTER FOR SOLAR SYSTEM STUDIES: 2019 JANUARY-APRIL

Brian D Warner et al. Minor Planet Bull. 2019.

Abstract

Lightcurves for 24 near-Earth asteroids (NEAs) obtained at the Center for Solar System Studies (CS3) from 2019 January-April were analyzed for rotation period, peak-to-peak amplitude, and signs of satellites or tumbling. Two asteroids, (381677) 2009 BJ81 and (454177) 2013 GJ35, were found to have two periods that make them additional candidates for the class of very wide binary asteroids. Another object with two periods was (18736) 1998 NU, 2.4753 h and 11.95 h. The second period solution is weak but does not seem to be systematic in nature. Potential tumblers include (88254) 2001 FM129, (90403) 2003 YE45, and 2006 SK134.
