GRB 060505 was the first well-observed nearby possible long-duration GRB that had no associated supernova .
Here we present spatially resolved spectra of the host galaxy of GRB 060505 , an Sbc spiral , at redshift z = 0.0889 .
The GRB occurred inside a star-forming region in the northern spiral arm at 6.5 kpc from the center .
From the position of the emission lines , we determine a maximum rotational velocity for the galaxy of v \sim 212 km s ^ { -1 } corresponding to a mass of 1.14 \times 10 ^ { 11 } M _ { \odot } within 11 kpc from the center .
By fitting single-age spectral synthesis models to the stellar continuum , we derive a very young age for the GRB site , confirmed by photometric and H \alpha line measurements , of around 6 Myr which corresponds to the lifetime of a 32 M _ { \odot } star .
The metallicity derived from several emission line measurements is lowest at the GRB site with 1/5 Z _ { \odot } but roughly solar in the rest of the galaxy .
Using the 2dF galaxy redshift survey we can locate the host galaxy in its large scale ( \sim Mpc ) environment .
The galaxy lies in the foreground of a filamentary overdensity extending south west from the galaxy cluster Abell 3837 at z = 0.0896 .
The properties of the GRB site are similar to those found for other long-duration GRB host galaxies with high specific star formation rate and low metallicity , which is an indication that GRB 060505 originated from a young massive star that died without making a supernova .
