Flux calibrated images of the known supernova remnant G 34.7-0.4 in basicoptical emission lines are presented. The low ionization images show arelatively flat flux distribution. The diffuse and patchy morphology of thedetected optical emission may indicate the presence of turbulent magneticfields. Typical observed Halpha+[N II] fluxes are ~8 x 10^{-17} erg s^{-1}cm^{-2} arcsec^{-2}, while the [S II] fluxes are lower around 4 x 10^{-17} ergs^{-1} cm^{-2} arcsec^{-2}. Emission in the medium ionization line of [O III]5007 A is not detected within our sensitivity limits, probably due to the heavyextinction towards the remnant. The long-slit spectra reveal strong [S II] and[N II] emission relative to Halpha and moderate [O I] 6300 A emission. Shockvelocities in the range of 110-150 km/s and low electron densities areestimated. Archival MSX infrared data show emission in the south and west areasof the remnant matching rather well the optical and radio emission.Comment: 6 pages, 4 figures, accepted for publication in A&
