A series of related active regions during January 14 – June 1, 1969

The history of a series of active regions is traced for the first half of 1969. At least four active regions successively occupied positions near Carrington longitude 270. In some cases the emergence of new regions in the midst of old regions was observed. All the larger flares observed in the studied region were associated with inverted polarity. In some cases the fields emerged inverted; in other cases the inverted polarity appeared to result from the interaction of emerging flux with fields already present at the surface.
