Query: Ring Type Structures in the Planck map of the CMB   We present the results of the quest for ring-type structures on the maps
observed by the Planck satellite. The results show that the vicinity of one
radius ({\gamma} = 0.14 radians) of the rings is distinguished. Twisting the
circles into deformed ellipses gives a pronounced drop of significance with the
increase of twisting.
