Scientific paper

Variable C is one of the Hubble-Sandage variables in M 33. Photometric and spectroscopic observations obtained during one of its rare maxima show that Variable C's variations are typical of luminous blue variables, especially those of the S Doradus type. Its spectrum at maximum light suggests a temperature of 7500 K for its expanding optically thick pseudophotosphere, which may be the coolest temperature yet measured for a luminous blue variable at maximum. A mass loss rate of 0.00004 solar mass/yr is determined from the IR excess and from the H-alpha emission, which is typical of these variables at maximum. Its bolometric luminosity is -9.8 mag and at maximum Mv is also -9.8 mag.
