comet and spectroscopic observations on 8 april

the eyes of the comet observers are all focused on comet C/2019 Y4 (ATLAS). The observation conditions are not optimal due to the disturbing moonlight and humidity in the air. Some comets were observed, among them: C/2017 T2, C/2019 N1, C/2019 Y4, C/2020 A2. With the C11 and LHiResIII spectrograph, some Be stars were observed for the H-alpha area in higher resolution (R=15,000): V801 Cas, 1107 Cam, HD 24479, HD38010.
