CCD Photometry and Lightcurve Analysis of Main-Belt Asteroids 14 Irene 4874 Burke, 1985 Hopmann, 3017 Petrovic, and 3070 Aitken from Observatori Carmelita in Tiana
Abstract
Observations carried out from 2011 December to late 2012 March allowed us to determine the synodic periods of 14 Irene, 1985 Hopmann, 3017 Petrovic, 3040 Aitken, and 4874 Burke. For 14 Irene, a period of 15.038 ± 0.002 h was found with an amplitude A = 0.10 mag, well in accordance with other published estimates. 1985 Hopmann exhibited a rotational period of 17.476 ± 0.003 h, A = 0.44 mag. 3017 Petrovic exhibited a rotational period of 4.080 ± 0.001 h, A = 0.62 mag. 3070 Aitken showed a period of 6.390 ± 0.005 h, A = 0.59 mag. For 4874 Burke we found a short rotational period of 3.657 ± 0.001 h with A = 0.31 mag.
