Collaborative Asteroid Photometry from UAI: 2020 January-March

Photometric observations of eight main-belt and one near-Earth asteroid were made in order to acquire lightcurves for shape/spin axis models. The synodic period and lightcurve amplitude were found for 78 Diana: 7.2940 ± 0.0006 h, 0.06 mag; 81 Terpsichore: 10.946 ± 0.002 h, 0.14 mag; 118 Peitho: 7.8066 ± 0.0006 h, 0.23 mag; 755 Quintilla: 4.550 ± 0.001 h, 0.04 mag; 782 Montefiore: 4.0726 ± 0.0002 h, 0.51 mag; 1052 Belgica: 2.7094 ± 0.0001 h, 0.08 mag; 3998 Tezuka: 3.08 ± 0.01 h, 0.49 mag; 7132 Casulli: 3.5238 ± 0.0002 h, 0.14 mag; (52768) 1998 OR2: 4.111 ± 0.001 h, 0.30 mag. We also confirmed the binary nature of the asteroid 1052 Belgica and detected the binary nature of the asteroid 7132 Casulli.
