We present lightcurve observations and multiband photometry for 107P/Wilson-Harrington using five small- and medium-sized telescopes. The lightcurve has shown a periodicity of 0.2979 day (7.15 h) and 0.0993 day (2.38 h), which has a commensurability of 3:1. The physical properties of the lightcurve indicate two models: (1) 107P/Wilson-Harrington is a tumbling object with a sidereal rotation period of 0.2979 day and a precession period of 0.0993 day. The shape has a long axis mode (LAM) of L-1:L-2:L-3 = 1.0:1.0:1.6. The direction of the total rotational angular momentum is around lambda = 310 degrees, beta = -10 degrees, or lambda = 132 degrees, beta = -17 degrees. The nutation angle is approximately constant at 65 degrees. (2) 107P/Wilson-Harrington is not a tumbler. The sidereal rotation period is 0.2979 day. The shape is nearly spherical but slightly hexagonal with a short axis mode (SAM) of L-1:L-2:L-3 = 1.5:1.5:1.0. The pole orientation is around lambda = 330 degrees, beta = -27 degrees. In addition, the model includes the possibility of binary hosting. For both models, the sense of rotation is retrograde. Furthermore, multiband photometry indicates that the taxonomy class of 107P/Wilson-Harrington is C-type. No clear rotational color variations are confirmed on the surface. (C) 2011 Elsevier Inc.
