  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 hour) and 0.0993 day
(2.38 hour), 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 L1:L2:L3 = 1.0:1.0:1.6. The
direction of the total rotational angular momentum is around {\lambda} =
310{\deg}, {\beta} = -10{\deg}, or {\lambda} = 132{\deg}, {\beta} = -17{\deg}.
The nutation angle is approximately constant at 65{\deg}. (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 L1:L2:L3 = 1.5:1.5:1.0. The pole orientation is around {\lambda}
= 330{\deg}, {\beta} = -27{\deg}. 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.
