(DACs) in UV resonance lines  which are thought to diagnose large scale coherent wind  anisotropies \citep{1996ApJ...462..469C,2008ApJ...678..408L},  or the less coherent line profile variability mentioned above \citep{1996ApJS..103..475F,1997A&A...327..699F}. \citep{1996ApJS..103..475F,1997AA...327..699F}.  Also non-thermal X-ray emission of OB main sequence stars has been proposed to relate  to surface magnetic fields \citep[e.g.,][]{1997ApJ...485L..29B,2002ApJ...576..413U}. \citep{1997ApJ...485L..29B,2002ApJ...576..413U}.
