The results of experimental observation of a speckle pattern of light propagating through multimode optical fibers coiled into spiral are presented. The rotation of the speckle pattern has been observed. It has been shown that the angle of the speckle pattern rotation (in radians) is numerically equal to the solid angle (in steradians) subtended by the trajectory tangential vector at the unit sphere.
