Abstract

We present low-dispersion visible spectra of two regions of the 30 Doradus nebula. When corrected for atomic continuum emission and divided by the spectrum of the exciting and illuminating stars, one of the two spectra clearly shows Extended Red Emission (ERE) superimposed on the scattering component. This ERE band peaks around 7270 \AA and is 1140 \AA width. HAC grains are found to explain the observed spectra in terms of scattering and luminescence.
