  NSV 11154 has been confirmed as a new member of the rare hydrogen deficient R
Coronae Borealis (RCB) stars based on new photometric and spectroscopic data.
Using new photometry, as well as archival plates from the Harvard archive, we
have constructed the historical lightcurve of NSV 11154 from 1896 to the
present. The lightcurve shows the sudden, deep, irregularly spaced declines
characteristic of RCB stars. The visible spectrum is typical of a cool (Teff <
5000 K) RCB star showing no hydrogen lines, strong C2 Swan bands, and no
evidence of 13C. In addition, the star shows small pulsations typical of an RCB
star, and an infrared excess due to circumstellar dust with a temperature of
~800 K. The distance to NSV 11154 is estimated to be ~14.5 kpc. RCB stars are
very rare in the Galaxy so each additional star is important to population
studies leading to a better understanding the origins of these mysterious
stars. Among the known sample of RCB stars, NSV 11154 is unusual in that it
lies well above the Galactic plane (5 kpc) and away from the Galactic Center
which suggests that its parent population is neither thick disk nor bulge.
