The HI supershell GS061+00+51 and its neighbours.

Abstract (from CDS):

We describe HI observations of a 4°x4° field in the Milky Way centered on l=61°, b=0° made by the Effelsberg radiotelescope. The field contains one previously identified HI supershell, GS061+00+51 (Heiles, 1979ApJ...229..533H); apart from it we find several new structures. We also study the HI distribution in the vicinity of four HII regions, S86, S87, S88 and S89. We confirm the existence of the shell GS061+00+51, and we find that it has two smaller neighbours, spherical shells with Rsh∼30pc. We identify at least one more regular shell at vLSR=-18km/s; and one blown-out shell at vLSR=-54km/s. In two cases we are able to connect HII regions with features in the HI distribution (S86 and S87), in two other cases no connection is found. Apart from quite regular HI shells we see a number of non-coherent objects, which are probably a result of the turbulence in the interstellar medium.
