3A0729+103 (= BG CMi) is an intermediate polar discovered through its X-ray emission (McHardy et al. 1981, 1984). The orbital period is 3235 hours and the rotation period is 15.2 minutes. For ephemeris and references on the source, reference is made to McHardy et al. (1984). This paper reports on optical (4025 to 5090 A) and ultraviolet (1200 to 3200 A) spectroscopy obtained, respectively, on Dec. 1, 1984 and Apr. 21, 1985. The data show clear modulation of spectral features with the orbital period.
