Scientific paper

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 March 14-17, 1990. From the resulting light curves, the rotation period of Dubiago was obtained for the first time and found to be 14.3 + or - 0.1 hr, while the previously reported rotation periods for Hektor (6.921 hr) and Chiron (5.92 hr) are consistent with the present results. Light curve amplitudes of 0.22 + or - 0.02 mag for Hektor, 0.23 + or - 0.02 mag for Dubiago, and 0.07 + or - 0.02 mag for Chiron were derived.
