HD 93521 is an example of the hottest end of the Be range. Hubble Space Telescope (HST) observations show evidence for a disk. This main sequence O star will provide a good test of the effects of spectral type on the iron (Fe) line depolarization. It is located at a high galactic latitude (l~60) and so may also show effects of interstellar polarization.
