Lightcurve Photometry, H-G Parameters and Estimated Diameter for 1412 Lagrula

Photometric observations of main-belt asteroid 1412 Lagrula were made over ten nights during 2013 March and April, with filtered system. The resulting synodic period is 5.9176 ± 0.0001 h with an amplitude of 0.28 ± 0.05 mag. The color index V-R = 0.37 ± 0.05 mag. The measured absolute visual magnitude, Hv = 11.81 ± 0.04 mag. and the slope parameter, G = 0.135 ± 0.049, are consistent with a low albedo object, e.g., type C. The diameter is estimated to be D = 23 ± 3 km.
