Query: Synchrotron superbubble in the galaxy IC10: the ionized gas structure,
  kinematics, and emission spectrum   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
[SII](6717+6731)A lines, long-slit spectroscopy, and spectroscopy with a
scanning Fabry--Perot interferometer. We have identified a bright (in the [SII]
lines) filamentary optical shell and determined its expansion velocity, mass,
and kinetic energy. The nature of the object is discussed.
