Abstract
Recently, it has been claimed that the recurrent nova T Pyxidis exhibits oppositely directed jets of ejecta apparent in features seen in Hα emission. Here we demonstrate that these features are in fact emission in the [N II] lines that lie on either side of Hα and arise from the expanding shell associated with this object rather than from collimated jets. We estimate an expansion velocity along a line of sight through the center of the shell of about 500 km s^(-1).
