Abstract The large sunspot group in Hale region 17098 was in the decaying phase of its development when a new flux emerged in its middle part on 3 September 1980. This region displayed chromospheric activity all that day. By the next day the spot of highest velocity (0.37 km s−1) formed a delta-configuration with one of the spots of following polarity of the old group. The centre of the observed flares was not in the vicinity of this spot moving parallel to the magnetic zero-line, it was in the western part of the group, where two spots were moving nearly perpendicularly to the magnetic zero-line (v=0.09 km s −1), and deformed the border of a gulf of opposite polarity. With the changing configuration the form of the observed flares also changed.
