Abstract
Extended spectroscopic datasets of several late-B stars of luminosity class Ia revealed the presence of similar peculiarities in their H alpha profiles, which might be interpreted as indications of deviation from spherically symmetric, smooth wind approximation. Surface structures due to non-radial pulsations or weak, large-scale, dipole magnetic fields might be responsible for creating wind structure in the envelopes of these stars.
