Abstract. GS 100-02-41 is a large neutral hydrogen (HI) shell located in the outer part of the Galaxy, at a distance of 2.8 kpc from the Sun.From an analysis of the HI data several parameters that characterize the structure have been determined. Based in energetic considerations, we estimated that GS 100-02-41 could have been originated for the join action of stellar winds and supernova explosion of the stars members of Cep OB1.
