We investigate the emission from the 22.2 GHz maser line of water, and compare it to the visual light curve for the semi-regular variable star RX Boo.  There appears to be a correlation between the maser emission and light curve, however, the correlation is not as clear as for the regular Mira variables.  The water emission appears over a broad velocity range, and separate features appear to react to the changing light with different time delays.
