again a clear and cold night (minus 3 degrees) i could observe several comets: 78P/, 88P, 114P, 124P, 155P, 246P, C/2010 U3, C2017 T2, C/2019 N1, C/2019 Y4, C/2020 A2, P/2019 Y2 (not detected). I observed several Be-stars with the LHiResIII spectrograph: 46 Per, HD 65873, HD 98058, Phecda, V581 Per.

during this clear night and no moon, i could observe several comets: 78P, 114P, 124P, 155P, 246P, C/2010 U3, C/2017 T2, C/2019 Y4, C/2020 A2. Witrh the C11 + LHiResIII (2400 l/mm grating) is could obtain high resolution spectra of the H-alpah region of Be-stars: CQ Uma, CT Cam, HD 24479, V416 Aur.

during this clear night, i made observations of Be-stars for H-alpha detail in high resolution. Starch which a spectrum is obtained are: Pleione, HD 50083, HD 34921, 1229 Aur – HD 50658
spectroscopic observation on 4 febr. 2020
in the late evening i started with taken a spectrum of Be-star HD 20134 with C11 + LHiResIII spectrograph with 2400 l/mm grating for H-alpha line detail.
