[1] The X-ray telescope aboard the satellite identified an uncatalogued fading source.

Around 2.5 hours after the burst trigger, a series of observations was carried out by the Gemini North telescope, which detected a bright object in the infrared part of the spectrum.

No evidence of a host galaxy was found either by Gemini North or by the Hubble Space Telescope.

[1] Though this burst was detected in 2009, it was not until May 2011 that its distance estimate of 13.14 billion light-years was announced.

With 90% likelihood, the burst had a photometric redshift greater than z = 9.06, which would make it the most distant GRB known, although the error bar on this estimate is large, providing a lower limit of z > 7.
