Interstellar extinction toward MWC 148
Abstract
We analyse high resolution optical spectra of MWC148 (optical counterpart of the gamma-ray source HESS J0632+057) obtained at Observatoire de Haute Provence and Rozhen Observatory. We measure equivalent widths of 7 diffuse interstellar bands and estimate the interstellar extinction EB-V=0.85 +/- 0.08.
