		| Abstract: | 
		T Pyx is a recurrent	nova which has	undergone eruptions on an almost regular basis every 20 years, until reaching a long lasting quiescence between 1967 and 2011. We observed the long awaited 2011 explosion	 in the optical and near infrared with	 intermediate spectral resolution. In this paper we report	on	 the change in the spectral type of	 the nova (both during its rise and fading), as  well as the observed	  changes in the expansion velocities.  We also present an interpretation of these changes and set them in the general	 framework of a new understanding of nova classification. |
