HR 1991. A new variable B star.
Abstract
HR 1991 was found to be a small amplitude variable from observations made in the Str6mgren uvby system. A period analysis of the light variation revealed the existence of a period of 2.644 d, but in addition irregular variability is present. The photometric characteristics of HR 1991 resemble those of magnetic and/or spectrum variables. Key words: new variable - uvby photometry
