An international collaboration of observers from North America and Europe presents a lightcurve of the Earth commensurate asteroid 357 Ninina that shows a synodic rotation period 36.00 ± 0.01 hours, amplitude 0.08 ± 0.01 magnitudes with a single deep minimum in an otherwise nearly flat lightcurve

Photometric observations of five asteroids were made in order to acquire lightcurves for shape/spin axis modeling. Synodic periods and lightcurve amplitudes were found for 1166 Sakuntala, 1929 Kollaa, 3443 Leetsungdao, and 2020 DB5. We also found color indices for 294 Felicia, 1166 Sakuntala, and 2020 DB5

A Comprehensive Photometric Study of 603 Timandra

Pages 121-124

Based on 65 sessions 2022 Sept. 24 - Dec. 28, we find for 603 Timandra a synodic rotation period of 330.1 ± 0.5 hours and amplitude 0.80 ± 0.05 magnitudes. There is also low-level tumbling with a possible second period of 273 hours, PAR -2. The period, amplitude, and epoch of lightcurve maximum all agree with a recent posting on the DAMIT website. Data obtained on 2022 Oct. 15 show that (B-V) = 0.80 ± 0.04 and (V-R) = 0.51 ± 0.02. At midlight, H = 12.18 ± 0.14 in the V band, G = 0.20 ± 0.17.
