Description
We present the photometric history of some Luminous Blue Variable
candidate stars in M 33. The search for outbursts was made in
photographic plates taken in the B band of the galaxy M 33 and cover an
eight year period, 1982-1990. Twenty five plates, separated into seven
groups, have been used. CCD UBV magnitudes of the star UIT003 are
presented also. Only one (of 12) of the LBV candidates (UIT003) presents
clear variability above the noise. The combination of photometric
variability and a typical LBV spectrum make it a new LBV. We present
also the light curves of Hubble-Sandage Variables A, B, C and 2.
