We present spectra covering the wavelength range 990 < \lambda < 1190Å\ for the LMC O9.7 Ib star HD 268605 (= Sk -67 005). The observations illustrate the high quality of data currently available from FUSE. They also demonstrate the capabilities of FUSE\/ to provide time resolved spectroscopy of wind and photospheric lines never before explored for temporal variability in a systematic manner. The observations span several days, with one continuously sampled interval of more than 4 hours.

The mean spectrum also serves as an excellent example of the dense information content of the FUSE\/ spectral region. It contains a wealth of both stellar and interstellar lines which cover a wide range of ionization and, hence, physical conditions.

This work is supported by NASA contract NAS5-32985.
