Abstract (from CDS):

We present spectroscopy of an extremely blue star found in the Galactic globular cluster NGC 2298. Previous CCD photometry gave a magnitude V = 18.79 ± 0.15 and a color B - V = -0.34 ± 0.10. Our visual spectrum reveals a number of He II and H I absorption lines, indicating that this object is a hot helium-rich subdwarf O star, similar to the He-sdO stars found in the Galactic halo.
