We have obtained spectra of the reflection nebulosity illuminated by t
wo heavily embedded IRAS sources in the L1641 molecular cloud, Re 50 a
nd IC 430 (V883 Ori). Examination of these spectra in combination with
their other properties indicates that these objects are FU Orionis ob
jects. Our spectrum of L1551 IRS 5 confirms the FU Ori classification
made for this star by Mundt et al. (1985).
