OPTICAL OBSERVATIONS OF THE UNUSUAL INTERACTING BINARY V644 MONOCEROTIS (HD 51480)

New optical spectroscopic and UBV photometric observations of the bright Be/shell star V644 Mon (HD 51480) are presented. The object, which has been described as an interacting binary system, exhibits strong, variable Balmer emission as well as numerous metallic emission features in the blue. No signs of absorption features due to any late-type companion are seen at wavelengths below 6500 A.
