Abstract (from CDS):

Neutral hydrogen 21-cm observations obtained with the 100-m Effelsberg telescope have disclosed a HI bubble surrounding the WN6-7 star WR149, located in the far side of the Perseus spiral arm. With a radius of 57pc and an expansion velocity of about 10km/s, this new bubble appears similar to those previously found around other Wolf-Rayet stars. Since stars of WN6-7 spectral sub-type are often found in open clusters and associations, we suggest that the observed HI bubble may be related to an undetected OB association. A second HI void in the neighbourhood is briefly discussed.
