Lightcurve Based Rotational Period Determination for Asteroids 1579 Herrick and 2171 Kiev
Abstract
We present results for rotational period determination using lightcurves for two asteroids observed during the first half of 2020. For 1579 Herrick we obtained P = 9.196 ± 0.002 h and amplitude A = 0.12 ± 0.03 mag, for 2171 Kiev we obtained P = 3.1714 ± 0.0002 h and amplitude A = 0.14 ± 0.08 mag. We also found evidence for the presence of a secondary period P2 = 23.38 ± 0.03 h.
