Astrometrically registered maps of HO and SiO masers toward VX Sagittarii.

The supergiant VX Sagittarii is a strong emitter of both HO and SiO masers. However, previous VLBI observations have been performed separately, which makes it difficult to spatially trace the outward transfer of the material consecutively. Here we present the astrometrically registered, simultaneous maps of 22.
