Using non-LTE extended and expanding model atmospheres, we find a surprisingly high mass-loss rate dot-M = 1.8 +/- 0.5 x 10-5 solar mass/yr and an effective temperature Teff = 42.5 +/- 2.5 kK. With the observed visual magnitude, this implies a radius R* = 17 +/- 2 solar radius and a solar luminosity L = 8.5 +/- 1 x 105 solar luminosity. We discuss possible sources of the uncertainties in the derived stellar parameters and conclude that the effective temperature may be underestimated; however, if so, the value of the mass-loss rate would not be affected.
