Scientific paper

We present the high-resolution (R=60000) NIR spectrum of P Cyg in the spectral range 996-1015 nm. The main spectral features are described, with special emphasis on the high-excitation FeII 999.7 nm emission line. We analyse the velocity field of the different features in the light of possible regions of their formation. We briefly review the appearence and variability of the 999.7 nm line in early-type stars and discuss possible excitation mechanisms.
