GCN Circular 4792

N. Mirabal (U. Michigan) and J. P. Halpern (Columbia U.) report on behalf
of the MDM Observatory GRB follow-up team:

"We obtained a low-resolution spectrum of the optical afterglow and
host galaxy of GRB 060218 using the MDM 2.4m telescope and Boller &
Chivens (CCDS) Spectrograph on Feb. 20 02:20 UT.  Strong, narrow emission
lines of H-beta, [O III] 4959,5007, and H-alpha at z=0.0331 are seen,
superposed on a blue continuum, which is still much brighter than the
SDSS pre-burst magnitudes.  The line ratios are typical of a high-excitation 
starburst.  This confirms the low-redshift, extragalactic nature of this
unusual GRB.
