Scientific paper

The C IV doublet in spectra of the dwarf nova HL CMa shows strong P Cygni profiles during the late rise, peak and decline from outburst maximum. Very high velocity emission wings are seen in some spectra. The N V, Si III and Si IV lines generally show blueshifted absorption with very weak emission components. Models of the ionization state of the wind provide a basis for discussion of the wind geometry.
