Resumen:
In this work we have made a multifrequency study of a newdetected HI supershell (GS100-02-41) in the outer part of theGalaxy. This feature is located at a distance of 4.6 +- 0.8 kpcfrom the Sun.  We have studied the interaction of GS100-2-41 withthe intesrtellar medium looking for evidence of induced starformation.  Four HII regions are seen projected onto the HI structure.  Anexcelent correlation between the neutral hydrogen supershell (SC-HI)emission, 408 MHz and 1420 MHz continuum emission has beenfound. Furthermore there is good correlation between SC-HI andinfrared (60 microns).We have used the all sky HI survey (Kalberla et al. 2005), The CGPS(Canadian Galactic Plane Survey), the 408 MHz (Haslam et al. 1982) and the1420 MHz (Reich P. and Reich W. 1986) surveys. Images at 8.25 microns  were takenby MSX satellite. IRIS 60 microns  was another survey used in this work.
