The planetary nebula NGC 246 has a high degree of symmetry about its central star, and can be described most graphically as a filled disk. Direct images of NGC 246 reveal a relatively homogeneous distribution of gases, with an unusual morphological feature that appears to contain less of the nebular material. At the center of this roughly circular feature, in the southeast quadrant of the nebula, there is a star (hereafter referred to as “the program star”). The placement of the program star is very suggestive of a wind blown cavity in the PN. The question of whether this star actually is interacting with the nebula, or merely along the line-of-sight, is addressed here for the first time.
