General Description

• The wind of the alpha scorpii A component - an M1.5 super giant, V~1m
   - excited by the B component - a B4 main sequence star, V~5.5m, 2.9" separated at
   position angle 275 deg. - should be observed in the whole spectral range. 21 slit
   positions with the slit aligned perpendicular to the connecting line of the two
   components should be observed, starting between the two stars wandering beyond the
   weaker component in steps of 0.5". We expect emission line spectra getting weaker
   to the ends of the slit. The 5th offset position should contain the spectrum of
   the B-star, too. Beyond the B-star the whole emission line spectra are getting weaker.
   We expect strong Fe emission lines at least near the B component. The geometry and
   the strength of emission lines of other elements, if present, are unknown. The last
   offset position of every OB is located at a distance of 60" to get a sky spectrum
   without wind lines.
  For the acquistion: we do not expect the B component to be seen due to the brightness
   difference and the strong density filter. Even if it is seen the acquisition must
   be conducted with the brighter A component because all offset positions are relative
   to this star.
