Abstract:
    We present observations of the nearby tidal dwarf galaxy Holmberg IX
    in M81 galaxy group in narrow band [SII] and Hα filters, carried
    out in March and November 2008 with the 2m RCC telescope at NAO
    Rozhen, Bulgaria. Our search for resident supernova remnants
    (identified as sources with enhanced [SII] emission relative to their
    Hα emission) in this galaxy yielded no sources of this kind,
    besides M&H 10-11 or HoIX X-1. Nevertheless, we found a number of
    objects with significant Hα emission that probably represent
    uncatalogued HII regions.
