The water maser emmision of
R Draconis was observed at 22 GHz at the Haystack Observatory approximately
once each month from November 1988 to July 1990.There is a correlation between the variations of the maser
emission and the AAVSO light curve; the peak of the maser activity follows the
light activity by about 0.2 period.
