Zusammenfassung:Spectral observations of the novalike star TT Ari at the Byurakan Observatory in September 2001 are reported. In most cases these results are in good agreement with earlier observational data. Some interesting differences from the earlier results were obtained, in particular the absence of emission and the presence of very weak absorption in the H^sub γ^ line. Another interesting difference that was recorded is the absence of an anti-P Cygni H^sub α^ line profile along with rapid variations in the P Cygni profile during our observations.[PUBLICATION ABSTRACT]
