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 14h3 ±0h1, while the previously reported rotation periods for Hektor (6h921) and Chiron (5h92) 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.
