On the base of the co-operation with several members of the ARAS group (Ch. Buil, St. Charbonnel, B. Heathcote, H. Kalbermatten, C. Sawicki, T. Lester, V. Desnoux, F. Houpert, M. Leonardi, J. Guarro) and other observers it was possible, to publish an article at IBVS about the "Variability of the HeI 6678 emission in delta Sco".

Thank you to all for the contributions of their spectra!
The investigation will be continued during the next years.

Nice article Ernst! Del SCO is one of my favorite Be stars to catch spectra on.
