We have observed 22 GHz water maser emission for T UMa at Haystack Observatory about once a month since December 14, 1986. The data have been compiled and graphed as a function of time and compared to the visual data compiled by the AAVSO. The variablilty of the maser emission and the visual light is comparable, but the maser emission shows a phase lag of 0.35 phase with respect to the visible.
