B. Gendre (LAM/CNRS/Universite de Provence), A. Galli (IASF-Roma/INAF),
M. Bo�r (OHP/CNRS) report :
Using the XRT analysis reported by Page et al. (GCN 7723), we
extrapolated an X-ray flux of 4.8 10^-13 cgi 1 day after the burst (2-10
keV). Using the Boer & Gendre relation, we estimate the redshift of GRB
080514B to be either 2.8 or 0.9 if this event is a group I or II
respectively (see Gendre, Galli & Bo�r, ApJ, in press), with
uncertainties of 30%. Further constraints on the redshift could be set
by B observations of the afterglow candidate reported in de Ugarte
Postigo et al. (GCN 7719).
