在1990年3月14日至17日期间，天文学家使用2.5米北欧光学望远镜对三颗小行星--624 Hektor、1167 Dubiago和2060 Chiron--进行了差分CCD测光。由光变曲线首次得到Dubiago的自转周期为14 h .3 ± 0 h .1，而Hektor（6 h .921）和Chiron（5 h .92）的自转周期与我们的结果一致.导出Hektor、Dubiago和Chiron的光变曲线振幅分别为0.22 ± 0.02 mag、0.23 ± 0.02 mag和0.07 ± 0.02 mag
Differential CCD photometry of three asteroids − 624 Hektor, 1167 Dubiago and 2060 Chiron − were carried out using the 2.5-m Nordic Optical Telescope on La Palma between 1990 March 14-17. From the resulting light curves the rotation period of Dubiago was obtained for the first time and found to be 14 h .3 ± 0 h .1, while the previously reported rotation periods for Hektor (6 h .921) and Chiron (5 h .92) are consistent with our results. Light curve amplitudes of 0.22 ± 0.02 mag for Hektor, 0.23 ± 0.02 mag for Dubiago and 0.07 ± 0.02 mag for Chiron were derived
