GRB 050803: Keck Observations
J. S. Bloom, D. Perley, R. Foley (UCB), J. X. Prochaska (UCSC), H. W.
Chen (MIT), & D. Starr (Gemini) report:
"R-band imaging of field of GRB 050803 (GCN 3748; 3757) with ESI/Keck
II shows several faint sources in the uncertainty circle of the XRT
(GCN 3752), including the extended object noted in GCN 3753.
Spectroscopy of this source reveals it to be a star forming galaxy at
z=0.422, based upon redshifted [OII], [OIII], and H-beta emission
lines. We expect ongoing analysis to improve the precision of this
redshift."
