H-alpha survey of nearby dwarf galaxies
  We present the H-alpha imaging data and flux measurements for 30 dwarf
galaxies in the Local volume. The H-alpha fluxes are used to derive the galaxy
star formation rate, SFR. The sample of observed galaxies is characterized by
the following parameters: the median distance of 7.5 Mpc, the median blue
absolute magnitude of -14.8 mag, and median SFR of -2.0 dex. Two dSph members
of the Local Group: Cetus and Leo IV do not show signs of star formation on the
rate of -5.4 dex and -7.0 dex, respectively. The BCD galaxy ESO 553-46 has one
of the highest specific SFR among the Local volume galaxies.
