22GHz observations of VX Sgr

DOI

We used MERLIN to observe 22-GHz H_2_O maser emission from the red supergiant VX Sgr in 1994 and 1999. The masers lie in a region 300-400mas in diameter. The angular size and the velocity distribution of the masers are similar at both epochs, although the total flux density in 1999 is only half of that seen in 1994.
