Possible Host Galaxy of GRB 050509b
Keck/DEIMOS spectrum of the possible host galaxy. The clear identification
of Ca H and K absorption, G band absorption, and MgI sets the redshift
at z=0.225. Note the absence of Hbeta or [OIII] emission. The spectral
features suggest that this is probably an early-type galaxy. Finally,
note that the wavelength solution at wavelengths less than 4500Ang is
the most uncertain due to the absence of strong arc lamp lines.
