Asteroids - Lightcurves - (3679) Condruses
33679 Condruses is a main-belt asteroid discovered by Debehogne at La Silla in 1984. A total of 723 data points were obtained over 29 nights during the period 2015 Sep 12 – Dec 12. The best fit lightcurve shows a period of 86.206 h ± 0.004 h and amplitude of 1.20 ± 0.01 mag. Pravec et al. (2015web) reported a period P > 32 h. Harris et. al (2014) suggest, due to the large amplitude, that the lightcurve shape will be bimodal. The period spectrum suggests that a period of 172.3 hours is also a possible fit, so the second lightcurve is preferred, with a period of 172.3 h ± 0.1 h and amplitude of 1.11 ± 0.01 mag, suggesting that the asteroid rotated 12 times during the period of observation. These findings were published in the Minor Planet Bulletin, Volume 44, Number 2, 2017 April - June.
