The First Byurakan Survey (FBS), also known as the Markarian survey, covers about 17000 sq. deg. It has been used by Markarian and his collaborators to search for UV excess galaxies (see Cat. ) and by Abrahamian and his collaborators to search for UV excess or emission line starlike objets. The identification, classification, and investigation of all blue stellar objects in the Survey constitutes the second part of the First Byurakan Survey and is a natural continuation of it. For this second program, at the present time, 4109 sq. deg. have been searched (33 < {delta} 61 deg, excluding the galactic plane) and a catalogue of 1103 blue stellar objects has been built. It has been published in a series of eleven papers referenced in the "References" section below. More details can be found in Mickaelian et al. 1999, Astrofizika 42,5: 'On the nature of the FBS blue stellar objects and the completeness of the Bright Quasar Survey'. Some accurate optical positions were measured by M. Veron, replacing the original FBS position.
