The 1600–2500Å spectra of many early-type supergiants are dominated by a broad depression of the continuum near 1920Å. This depression, often called the 1920Å feature, was detected in S2/68 (TD-1) spectra of early B stars (Thompson et al. 1974) and was shown to be strongly luminosity dependent. It was also shown that its profile could be matched by the cumulative effects of FeIII absorption lines.
