Scientific paper

Spectroscopic and photometric observations indicate a physical
association between the peculiar early-type emission-line stars HD
122669 and HD 122691. The latter has undergone a drastic change in the
strength of its emission lines during the past 20 years. There is some
indication that both stars vary with shorter time scales.
