摘要：

Photographic spectroscopic observations are presented of ρ Leo (HD 91316), a class B1 supergiant at high galactic latitude which shows little reddening. The interstellar diffuse features λ 4430, λ 5797 and λ 6283 are not detected. There is an indication in the spectra that λ 5780 might be present, with a strength consistent with the amount of reddening. Previous reports of anomalously strong λ 4430 are not confirmed. These were based on low-resolution spectroscopy and the explanation is that the appearance of a wide feature is produced by a combination of several weak atomic absorption lines in the spectrum of the star itself. © Royal Astronomical Society.
