Lightcurve Photometry and H-G Parameters for 1151 Ithaka
Abstract
Observers at three observatories worked in collaboration to obtain photometric observations of main-belt asteroid 1151 Ithaka over thirteen nights from 2011 August- October. The resulting analysis found a synodic period P = 4.93115 ± 0.00011 h with an amplitude AV = 0.12 ± 0.01 mag. The measured absolute visual magnitude, H = 12.94 ± 0.03 mag, slope parameter G = 0.05 ± 0.03, and color index V-R = 0.38 ± 0.03 mag are consistent with a low albedo C-type object. The diameter is estimated to be D = 14 ± 3 km.
