dc.descriptionPG 1002+506 is found to be a Be star, one of two so far found by the Palomar-Green survey. Its spectrum is classified as a B5 +/- 1 Ve, with Teff = 14,900 +/- 1200, log g = 4.2 +/- 0.2, and v sin i = 340 +/- 50 km/s. At b = +51 degrees, its height above the Galactic plane would therefore be Z = +10.8 kpc, putting this apparently young, rapidly rotating star well into the Galactic halo. Its heliocentric radial velocity is found to be -2 +/- 15 km/s, consistent with either having been formed in the Galactic disk and subsequently ejected, or having been formed in the halo.
