Rotational Period Determination for 23 Thalia, 204 Kallisto and 207 Hedda, and Notes on 161 Athor and 215 Oenone
Abstract
Synodic rotation periods and amplitudes have been found for: 23 Thalia 12.312 ± 0.001 h, 0.10 ± 0.01 mag; 204 Kallisto 19.489 ± 0.002h, 0.18 ± 0.02 mag; and 207 Hedda 30.098 ± 0.001 h, 0.09 ± 0.01 mag with 4 maxima and minima per cycle. For 161 Athor an amplitude 0.02 magnitudes is found near longitude 6 degrees, latitude -8 degrees, and for 215 Oenone an amplitude > 0.16 mag and long period probably >24h.
