Query: Outflow from and asymmetries in the nebula around the LBV candidate
  Sk-69 279   We present and discuss new long-slit Echelle spectra of the LMC LBV candidate
Sk-69 279 and put them in context with previous images and spectra. While at
first glance a simple spherically expanding symmetric shell, we find a
considerably more complex morphology and kinematics. The spectra indicate that
morphologically identified deviations from sphericity are outflows of faster
material out of the main body of Sk-69 279. The morphological as well as the
kinematic similarity with other LBV nebulae makes it likely that Sk-69 279 is
an LBV candidate, indeed, and poses the question in how far outflows out of
expanding LBV nebulae are a general property of such nebulae--at least during
some phases of their evolutions.
