We present observations of the HI tidal arm near dwarf galaxy NGC 3077
(member of the M81 galaxy group) in narrow band [SII] and H_alpha filters.
Observations were carried out in March 2011 with the 2m RCC telescope at NAO
Rozhen, Bulgaria. Our search for possible supernova remnant candidates
(identified as sources with enhanced [SII] emission relative to their H_alpha
emission) in this region yielded no sources of this kind. Nevertheless, we
found a number of objects with significant H_alpha emission that probably
represent uncatalogued, low brightness HII regions.
