Abstract
Photometric observations of three asteroids were conducted from the Astronomical Observatory of the University of Siena (Italy) in order to determine their synodic rotation periods. For (23621) 1996 PA, a Marscrosser asteroid, we found a period of 2.666 ± 0.001 h with an amplitude of 0.10 mag. For the two main-belt asteroids (29564) 1998 ED6 and (31775) 1999 JN122, we found, respectively, a period of 8.434 ± 0.002 h with an amplitude of 0.57 mag and a period of 4.319 ± 0.01 h with an amplitude of 0.12 mag.
