General Description

These observations are undertaken to unravel the evolution from O-type
 star to LBV to Wolf-Rayet. This proposal will specifically determine the dust properties
 and morphology of LBV-type stars verses WC-type WR stars.  We suspect that the dust
 production is a result of binary wind interactions.

Obsblocks A and B contain the observations of WR 76 which failed to schedule under
 the original program. Since both baselines are needed to properly interpret the
 data, if given a choice, we prefer that the stars lacking only the ut3ut4 baseline
 execute first, i.e. observation blocks C,D,E, and H.

Critical Observing Condition Constraints

WR 95 transits at sunrise on March 14,2005. We would be grateful for observations
 as close to transit as possible and we are willing to postpone observations until
 later if needed and possible. Unfortunately, cycle 76A does not correspond to the
 same time of year as 73A.
