Top: non-normalized CFHT ESPaDOnS spectra of nearby star HD 195810 and the strongly reddened star HIP 101364 in the 9428 Å DIB region. No continuum fitting nor telluric correction has been performed and the spectra are displayed in the geocentric frame. Departures are seen at centers of telluric lines due to different atmospheric water vapor altitude profiles. Outside those lines departures can be seen around the 9412 Å DIB Galazutdinov et al. (2000); Cordiner et al. (2017). Very weak departures may also be seen in the 9428 Å DIB region. Bottom: ratio of the two spectra. Strong telluric residuals are present (light blue regions), however two additional features are apparent: a complex structure around the 9412 Å DIB and a depression around 9428 Å. The dashed black vertical line indicates the expected position of the DIB based on laboratory results and the 9577 Å DIB (not shown) in the same spectrum. A Gaussian fit performed in unmasked regions (dark blue). The depth of the 9428 Å DIB is on the order of 2.5%, which should be consistent with the 7% depth of the 9577 Å DIB.
