We summarize the results of our Gegenschein and zodiacal light observations at Haleakala (altitude 3055 m, Hawaii) between the dates of 19 August and 25 September in 1995, at Norikura (altitude 2876 m, Japan) on 18 September 1996, and at Kiso (altitude 1130 m, Japan) between the dates of 9 February and 5 March in 1997. The instrument we used consists of a fish-eye lens or a wide angle lens attached to a cooled CCD camera with blue, green, and red filters. We have found a significant excess of the brightness near the antisolar point. The position of the maximum brightness of this excess (the Gegenschein) slightly deviated from the antisolar point to the south in September and to the north in February. On the other hand, the locus of points of maximum brightness of the evening zodiacal light is significantly shifted toward the north from the ecliptic plane. While the result of morning zodiacal light measurements obtained at Haleakala (altitude 3055 m, Hawaii) in September revealed the locus shifted toward the south. Our observed evidence suggests that these variations were caused by the annual motion of the Earth with respect to the plane of the zodiacal cloud. When the symmetric plane of the zodiacal dust cloud differs from the ecliptic plane, it is natural that the contour morphology of the Gegenschein and zodiacal light will vary with the season. Our model calculations for the zodiacal light suggest that our observed results of the Gegenschein agree with the predictions deduced from a cloud model having a symmetric plane on the invariable plane of the solar system.
