We report the spectroscopic confirmation of a compact Lyα emitting galaxy at . A FORS2 spectrum of the source shows a strong asymmetric line with a flux of erg s-1 cm-2, making it one of the brightest Lyα emitting galaxies at this redshift, and a line-of-sight velocity dispersion of 400 km s-1. We also have a tentative detection of a second, narrower component that is redshifted by 400 km s-1 with respect to the main peak. A FORS2 image shows that the source is compact, with a FWHM of 05, which corresponds to 3.2 kpc at this redshift. This source is a brighter example of J1236.8+6215 ([CITE], ApJ, 570, 92), another Lyα emit ting galaxy at .
