Zusammenfassung:We carried out photometric and spectroscopic observations of comet 29P/ Schwassmann-Wachmann 1 at the SOAR 4.1-meter telescope (Chile) on August 12, 2016. This paper presents the results of only spectroscopic analysis. The spectra revealed presence of CO\(^+\) and N\(_2^+\) emissions in the cometary coma at a distance of 5.9 AU from the Sun. The ratio [N\(_2^+\)]/[CO\(^+\)] within the projected slit seems to be 0.01. We have also estimated spectral gradient value for the comet.
