COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 2514 Konkoly Observatory Budapest 4 May 1984 HU ISSN 0374-0676 ADDITIONAL VARIABLE STARS IN THE NORTHERN LUMINOUS STARS CATALOGUES In IBVS No. 2112 (March 1982) the writer listed the stars in the six catalogues of Luminous Stars in the Northern Milky Way that were then known to him to be named or numbered suspected variables. With the publication of the New Catalogue of Suspected Variable Stars it has proved desirable to reinvestigate this matter, with the results given in Table I, which lists additional stars that have been newly catalogued as suspected variables and also contains a number of named variables that were overlooked in the previous work.
