摘要：

A period of 15.4 days, recently discovered by Stahl et al. from intensive monitoring of Halpha emission in theta1 Ori C during 1992-1993, has been found to phase large variations in the C IV lambdalambda1548, 1551 wind profile of this star previously reported from IUE high-resolution data obtained during 1978-1983. These stellar-wind variations are among the largest observed in O stars not known to be components of interacting binaries; the strict periodicity is unique among apparently single O stars and constitutes an important constraint on the unknown origin of the phenomenon.
