Visual spectroscopy of HR 5999 obtained over 15 years shows the object to be an A5-7 III-IVe star with an extended circumstellar atmosphere. It is suggested that HR 5999 and HR 6000 form a physical pair with a common age. The observations indicate that the photospheric radial velocity component is variable, and that sudden variations in the photospheric line components and/or shell components may occur. The decreasing brightness noted is found to be correlated with increasing H-alpha emission flux.
