Asteroid Lightcurve Analysis of Data from Dusty Files

Lightcurves for 14 main-belt asteroids were obtained at the Barnes Ridge Observatory from 2013 October through 2017 November. Synodic rotation periods and amplitudes are found for 9 of the 14 main-belt asteroids. The nine are 2381 Landi: 3.98595 h, 0.86 mag; 2884 Reddish: 14.310 h, 0.90 mag; 4067 Mikhel'son: 2.24620 h, 0.15 mag; 4517 Ralpharvey: 3.60065 h, 0.31 mag; 5613 Eizaburo: 2.87538 h. 0.35 mag; 5976 Kalatajean: 4.55362 h 0.59 mag; 14309 Defoy: 3.3940 h, 0.17 mag; (18017) 1999 JC124: 3.0300 h, 0.18 mag; (31775) 1999 JN122: 4.3186 h, 0.10 mag. Of the remaining five asteroids 4336 Jasnicwicz has a possible period of 10 h; (6045) 1991 RG9 has a possible period of 12.3 h and periods of 2736 Ops, 2902 Westerlund and (12721) 1991 PB could not be calculated.
