Abstract
We present preliminary analysis of the first far-ultraviolet observati on of the magnetic cataclysmic variable PQ Geminorum (RE 0751+14). The mean spectrum of PQ Gem obtained by the ORFEUS telescope shows strong , broad emission lines of C III, Ile II, and O VI and possibly other w eak lines within a structured continuum. The flat, overall continuum f lux distribution observed indicates the presence of a hot, extended ac cretion region in PQ Gem. Time-series analysis of the spectra reveals that the emission lines are highly variable on short timescales.
