| Abstract: | Using the Ha filtergrams obtained with our 26-cm telescope, we have analyzed the evolution of the magnetic structure and the spot proper inchon of a new emerging flux region from Dec. 5 to Dec.9, 1990. A rare phenomenon of a spot penetrating another one with the same magnetic polarity was observed. Although the pl spot was found to be squeezed, elongated and broken in the process of pentration, no violent activities were observed' Zwaan's new emerging spot model is difficult to directly explain the process of penetration, so a new model for spot emergence is needed to interpret the peculiar phenomenon. |
