Simple spectroscopic program divided in 4 parts (one part per target), aiming at taking long-term time series of Luminous Blue Variable stars in the SMC and LMC to study in depth the structure of the stellar wind and its variability. Each part (A,B,C,D) consists of identical OBs including a short exposure (to get H_Alpha without saturation) and a longer exposure, that may saturate (no problem for this). PI has provided an useful and informative 'book keeping sheet' (file: 69.D-0390A.002.ps). Requirements: observations should start as soon as possible (as early as May for the SMC target, and July for the LMC targets). It is important that observations are well distributed until the end of the period. Weekly frequency is optimal - cf corresponding README file for more info.
