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 0
5, 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
