Abstract

VBLUW photometry of field stars around the new LBV, WRA 751, is presented and discussed in order to determine its distance with the aid of the reddening-distance method. With a reddening for WRA 751 of E(B - V)J = 1.m45 - 1.m80; in which the circumstellar reddening of less-than-or-equal-to 0.m40 is taken into consideration, the distance should be r greater-than-or-equal-to 4 - 5 kpc, respectively, confirming Hu et al. s (1990) suggestion. VBLUW photometry of WRA 751 is also presented and discussed in order to analyze its variability. This shows a light amplitude of 0.m15 with a time scale of approximately 30d and superimposed short time scale variations (approximately a week) with amplitudes of approximately 0.m03.
