Several gamma-ray bursts (GRBs) have been observed in Serpens Caput, such as GRB 970111, one of the brightest GRBs observed. An optical transient event associated with this GRB has not been found, despite its intensity. The host galaxy initially also proved elusive, however it now appears that the host is a Seyfert I galaxy located at redshift z = 0.657.[121] The X-ray afterglow of the GRB has also been much fainter than for other dimmer GRBs.[122] More distant is GRB 060526 (redshift z = 3.221), from which X-ray and optical afterglows were detected.
