After some technical problems with the PC of the BRIXIIS-I observatory i could finally start with imaging on about 23u50 local time with comet observations: comets which are observed are: 68P/KLEMOLA, 123P/WEST-HARTLEY, C/2016 R2 (PANSTARRS), C/2019 D1 (FLEWELLING) , C/2019 G1 (PANSTARRS) , C/2019 F1 (ATLAS-AFRICANO). With BRIXIIS-II observatory, i could obtain some high resolution spectra of Be-stars and var.stars with the C11 and LHiResIII spectrograph: V357 Lac, HD 193182, gam Cas, omi And.
I want to start to obtain spectra of variable stars for AAVSO. Since a couple of months AAVSO have opened a spectrum database. As kind of verification AAVSO asked as first spectrum a spectrum of a star which they call a ‘standard star’ . So i took 2 stars from the list mu UMa and eta Boo. Also a spectrum of ALTAIR for the instrument response. Later i could also obtain 2 spectra of Be-stars: 28 Cyg and HD 194335.
During a short period of clear sky i opened the 2 observatories , 1 for comet Observations and second for spectroscopic observations of Be-stars. I could start about 23:00 local time (this period of the year are the nights very short): comets that are observed are: 123P, 149P, C/2017 K2, C/2016 R2. After about 1.5 hour, clouds where coming in i must interrupt the observations. Be-stars which are observed are: PHECDA, CQ Uma, HD 175863. (with LHiResIII and 2400 l/mm grating – R = +/- 14500)
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)
