Abstract (from CDS):

We present new photometric observations in Johnson V and B of WR30a, revealing relative dramatic changes in brightness of 0.2mag. These variations occur on a time scale of hours, and are only seen in V. We argue that they are not caused by dust extinction, but either by a dramatic change in the strength of the CIV 5801-12Å emission line doublet due to a de-excitation process, or by some unknown continuum effect.
