  Observations of the nebula S3 associated with the WO star in the galaxy IC
1613 and of an extended region surrounding S3 are reported. The star and bright
core of the nebula were observed with a multipupil fiber spectrograph mounted
on the 6-m telescope of the Special Astrophysical Observatory of the Russian
Academy of Sciences. Images in the principle spectral lines and integrated
spectra of the star and three compact clumps were obtained, and the
radial-velocity field constructed. An extended region of the galaxy was
observed with the Very Large Array at 21 cm. A giant ring or HI shell enclosing
a large fraction of the stellar population in IC 1613 was discovered. The WO
star and associated bipolar nebula, which we discovered earlier, lies at the
inner edge of the H ring. A local HI deficiency and two arc-like HI ridges were
also detected for the first time, and probably represent the neutral component
of the bipolar shell surrounding the WO star. The two arc-like ridges may also
have been produced by the collective stellar wind (and supernova explosions?)
in OB association No. 9 from the list of Hodge. A scenario for the formation of
the extended bipolar feature is discussed, based on the new data.
