HD 249179, previously cataloged as a possible X-ray binary, shows H-alpha, Paschen, and O I emission, weak V/R changes, two pulsation frequency groups, and no detected X-rays, pointing to a classical Be star with an active circumstellar disk.

A multi-epoch spectral and photometric study to understand the nature of the interesting Be star candidate HD 249179
