COMMISSION 27 OF THE I.A.U. INFORMATION BULLETIN ON VARIABLE STARS NUMBER 100 Konkoly Observatory Budapest 30 June 1965 BRIGHT SOUTHERN BV - STARS On sky patrol plates of Bamberg Southern-Station 12 further stars were found whose variability seems to be real as can be seen from the material available till now.
