after the cirruscumulus cloud cover was gone, i could start with observations of some Be-stars with the LHiResIII spectrograph (2400 l/mm grating) and C11 telescope: stars which are observed are: iot Lyr, theta Corona Borealis and Phecda.
during this clear evening, i could obtain spectra of several Be-stars: 59 Cyg, omi Her, HD 171780, kap Draconis.
Die the high clouds that are passing by in periods, i didn’t observe any comets, but i could obtain several spectra of Be-stars: 6 Cep, 28 Cyg, BK Cam, iot Lyr.
a very clear an transparant sky invited me to observe comets and spectroscopic observations of Be-stars as well. comets which are observed are: 68P/KLEMOLA, 149P/MUELLER, C/2010 U3 (BOATTINI), C/2016 R2 (PANSTARRS), C/2017 K2 (PANSTARRS), C/2018 U1 (LEMMON), C/2019 F1 (ATLAS-AFRICANO). Spectroscopic observations of Be-stars are: Sheliak, Alfirk, nu Cyg, HD 206773, HD 203374.
During this cold, but transparant eveningsky, i obtained some spectra with the C11 & LHiResIII (high resolution) setup (BRIXIIS-II observatory) of : VV Cep, HD 208682 , 4 Her. Also some comets are observed with the setup 0.4-m f/3.8 Newton with SBIG STL6303E CCD-camera (BRIXIIS-I observatory): 123P/(WEST-HARTLEY, 164P/CHRISTENSEN, 209P/LINEAR, C/2016 R2 (PANSTARRS), C/2019 F1 (ATLAS-AFRICANO)
Not a very transparant sky, but i started with spectroscopic observations of some Be-stars: gam Cas, tet CrB, 53 Boo, kap Dra, cx Dra.
clouds were coming, bu i could obtaine 2 spectra and 2 comets, after these observations clouds where coming in and i must interrupt the observations: comets which are observed are: C/2010 U3, 123P spectroscopic observations: VV Cep, Alfirk, HD 208682
again the new object was observed this time for 1 hour (30x120sec). This object was assigned as comet C/2019 F2 (ATLAS) on 22 apr. 2019 via MPEC 2019-H29 : COMET C/2019 F2 (ATLAS) issued on 22 apr. 2019. Be-stars which are observed are: HD 24479, HD 112028
again a clear warm night, i could start on 22h local time with observations of comets and also tha new object A10cu6N mentioned on the PCCP. Also some Be stars to abtain high resolution spectrum of the H-alpha part: CQ Uma, phi Leo, HD 138749
during this clear night i started to observe some comets also a new object A10cu6N , mentioned on the PCCP of the Minor Planet Center, for several weeks. Despite the 93 % moon i could catch this faint object with the 0.4-m f/3.8 telescope. spectroscopic observation of Be-stars was: HD 208682
