Phenomena Accompanying the Birth of Sunspot Pores

Abstract

Disturbances in the photospheric granulation accompanying the birth and development of some sunspot pores are illustrated (Plate 1) and described. The disturbances last for about 3 hr and take the form of a number of dark lanes lying between two groups of pores whose location with respect to the rest of the spot group suggests that they are of opposite magne1;ic polarities.
