E. O. Ofek, S. B. Cenko, and A. Rau (Caltech) report on behalf of a
larger collaboration:

The XRT error circle of GRB 070521 (Guidorzi et al. 2007; GCN 6431),
coincides with the outskirts of a nearby (z=0.0307) bright (i=14.6)
galaxy.

The XRT position is 30.7" from the galaxy center (19 kpc projected).

The SDSS coordinates of the galaxy are:
  	RA = 16:10:40.75
  	DEC= +30:15:18.5 (J2000.0)

For availbility of SDSS pre burst observations see Cool et al. (GCN 6432).
