The giant filamentary shell, DEM 171, is found to be expanding at approximately 37 km s −1 . A supernova and stellar wind origin are both explored as possible causes for the expanding shell. A stellar wind origin would imply a mass‐loss rate of the order of 10 −5 M ⊙ yr −1 , indicating that it could be caused by a Wolf–Rayet star. A number of blue stars are found to lie within the shell and one is identified as a Wolf–Rayet candidate.
