“…It is interesting that the systemic velocity for Puppis A of +5 km s −1 reported by Gosachinskij & Khersonskij (1985) is in close agreement with that of +7.6 km s −1 reported here. Nevertheless, the clearly defined H i envelope in fig. A12 of Gosachinskij & Khersonskij (1985) giving an expansion velocity of 8 km s −1 has not been reported elsewhere.…”

“…Sakhibov & Smirnov (1983) also used the radial velocity of this OB Association to obtain a kinematic distance of 2X2^1X0 1X90 X85 kpc to it and Puppis A. Gosachinskij & Khersonskij (1985) identified an H i envelope around Puppis A from data with a velocity resolution of 6.3 km s 21 . The velocity centre of this H i hole is at 15 km s 21 .…”

The 1667‐MHz ground‐state hydroxyl (OH) line has been observed towards positions on Puppis A as well as in the immediate vicinity of this supernova remnant (SNR). The spectra at two positions on Puppis A show absorption lines at velocities less than +7.6 km s−1, and emission lines above this velocity. Analysis of all four 18 cm OH lines indicates that Puppis A must lie between the OH clouds seen in absorption and emission, giving it a vlsr of +7.6 km s−1. This implies that the kinematic distance to Puppis A is The OH clouds in front of Puppis A are slightly anomalously excited, as shown by analysis of the four 18 cm OH lines at the two observed positions on Puppis A. There is no evidence of any interaction of the SNR with the clouds in front of and behind it.

“…The anomalously high kinetic energy of some HI shells surrounding classical supernova remnants (see, e.g., Gosachinskij and Khersonskij (1985), Gosachinskij (2005), and references therein) do not provide unequivocal evidence for a hypernova explosion either. First, the wind from the supernova progenitor and/or the stars of the host OB association is an obvious energy source of the outer H I shell.…”

We have investigated the structure, kinematics, and emission spectrum of the ionized gas in the synchrotron superbubble in the irregular galaxy IC 10 based on observations with the 6-m Special Astrophysical Observatory telescope with the SCORPIO focal reducer in three modes: direct imaging in the [S II] λ(6717 + 6731)Å lines, long-slit spectroscopy, and spectroscopy with a scanning Fabry-Perot interferometer. We have identified a bright (in the [S II] lines) filamentary optical shell and determined its expansion velocity, mass, and kinetic energy. The nature of the object is discussed.
