  Diffuse far-ultraviolet (FUV: 1370-1670 A) flux from the Taurus molecular
cloud region has been observed with the SPEAR/FIMS imaging spectrograph. An FUV
continuum map of the Taurus region, similar to the visual extinction maps,
shows a distinct cloud core and halo region. The dense cloud core, where the
visual extinction is A_v > 1.5, obscures the background diffuse FUV radiation,
while a scattered FUV radiation is seen in and beyond the halo region where A_v
< 1.5. The total intensity of H2 fluorescence in the cloud halo is I_{H2} = 6.5
x 10^4 photons cm^{-2} s^{-1} sr^{-1} in the 1370-1670 A wavelength band. A
synthetic model of the H2 fluorescent emission fits the present observation
best with a hydrogen density n_H = 50 cm^{-3}, H2 column density N(H2) = 0.8 x
10^{20} cm^{-2}, and an incident FUV intensity I_{UV} = 0.2. H2 fluorescence is
not seen in the core presumably because the required radiation flux to induce
fluorescence is unable to penetrate the core region.
