The 14-m Metsahovi radio telescope was used to monitor the 22.2-GHz emission of the strong water maser source W49N between December 1980 and June 1983 and between February and April 1985 with an observation time interval of about nine days. The observed spectra are given in the form of a spectral atlas covering the LSR velocity range of -330 to 220 km/s. In March 1983, a large flare with an isotropic luminosity of 0.15 solar luminosites was noted in a single 42-kHz-wide (FWHM) H2O line. The long-term variability and nature of the unpolarized H2O maser emission of W 49N are considered.
