GRB 091130B: SDSS galaxy at XRT location
2009-11-30T18:24:12Z (14 years ago)
Andrew Levan at U.of Leicester <>
A.J. Levan (U. Warwick), N.R. Tanvir (U. Leicester) report:

"Inspection of SDSS images of GRB 091130B (Racusin et al. GCN 10214)
shows a faint galaxy (r=22.5),  inside the XRT localization.
There is also a brighter galaxy (r=18.9) offset roughly 7" from the
XRT position (which has a 4.8" error radius). The detection of these
objects suggests that GRB 091130B could be a relatively low redshift
