Context. Luminous BA-type supergiants are the brightest stars in the visible that can be observed in distant galaxies and are potentially accurate distance indicators. The impact of the variability of the stellar winds on the distance determination remains poorly understood. Aims. Our aim is to probe the inhomogeneous structures in the stellar wind using spectro-interferometric monitoring. Methods. We present a spatially resolved, high-spectral resolution (R = 12 000) K-band temporal monitoring… Expand
