We report the first results for the latest outburst of the recurrent
nova T Pyx from the FIES echelle spectrograph on the 2.6 m Nordic
Optical Telescope (NOT) at La Palma from 3700-7200 A with a resolution
of 67000. The first spectrum, obtained on 2011 Apr. 15.92 UT during the
rise to maximum (V approx 9.5) with integration time of 600 sec with a
S/N of 30 at 6000 A (continuum), was sufficiently well exposed to
display some of the strongest optical diffuse interstellar bands (DIBs).
