It turned out to be a clear night and I was able to start comet observations with observatory I and simultaneously record some spectra of Be stars with observatory II.
Comets I observed were: 29P, 32P, 65P, 362P, C/2021 S3, C/2021 T4, C/2022E2, C/2023 A3 and C/2024 C4. Be stars where I obtained a high-resolution spectrum (R ~15000) in H-alpha region are: V380 Cep, HD 203025, Alfirk and 28 Cygnus.
