  We have fitted the Chandra Low Energy Transmission Grating spectrum of SS
Cygni in outburst with a single temperature blackbody suffering the
photoelectric opacity of a neutral column density and the scattering opacity of
an outflowing wind. We find that this simple model is capable of reproducing
the essential features of the observed spectrum with the blackbody temperature
T_bl = 250+/-50 kK, hydrogen column density N_H = 5.0^{+2.9}_{-1.5} x 10^{19}
cm^{-2}, fractional emitting area f = 5.6^{+60}_{-4.5} x 10^{-3}, boundary
layer luminosity L_bl = 5^{+18}_{-3} x 10^{33} erg/s, wind velocity v ~ 2500
km/s, wind mass-loss rate Mdot_w ~ 1.1 x 10^{16} g/s, and arbitrary values of
the wind ionization fractions of 20 ions of O, Ne, Mg, Si, S, and Fe. Given
that in outburst the accretion disk luminosity L_disk ~ 1 x 10^{35} erg/s,
L_bl/L_disk ~ 0.05^{+0.18}_{-0.03}, which can be explained if the white dwarf
(or an equatorial belt thereon) is rotating with an angular velocity Omega_wd ~
0.7^{+0.1}_{-0.2} Hz, hence V_rot sin i ~ 2300 km/s.
