Abstract: Using A-configuration of the BIMA-array with 0 to 4.4" angular resolution maps were obtained of the 107 GHz methanol line in W3(OH). The 107 GHz masers have their counterparts in another methanol transition at 6.7 GHz. The strongest maser spots are unresolved with the BIMA-array and are less than 0 to 4.15", which corresponds to the lower limit of the brightness temperature 5 x 10^5 K. A model of Class II methanol masers emitted in the extended atmosphere of icy planets orbiting around the O-star which excites H ii region is proposed.
