Figure 2

Spectra of MWC 930 obtained at the visual minimum dotted lines and maximum solid lines. The visual minimum spectra were obtained in October 2001 (upper panels) and July 2004 (lower panels). The visual maximum spectrum was obtained in June 2012 (all panels). The intensity is shown normalized to the underlying continuum, and the wavelengths are in Angstroms and heliocentric.
