During a short period of clear sky, i could obtain a high resolution spectra for H-alpha region of Be-star QR Vul.
comet and spectroscopic observations on 19 june.
the nights are now about the shortest of the year. It only gets really dark around 0:30UT. It was pretty much clear, with a cloud here and there. The 95% moon was interfering though, resulting in only an SQM in the zenith of 18.8. 2 comets: C/2019 T4 and C/2021 S3 were observed. 2 spectra of H-alpha region in high resolution, of Be stars: 58 Cyg and HD 208682 could be obtained.
comet observation on 11 june
Meanwhile, the nights here are already short and it only gets dark around 0h30, which is why I already start observations at dusk. I was able to observe comet C/2023 A3.
spectroscopic observations on 9 june
This evening I was able to obtain a spectrum from Be-ster V421 Cep.
spectroscopic observations on 26 may
Between the many showers and thunderstorms, there was a brief clearing and I was able to obtain 2 spectra with the C11 and LHIRESS III spectrograph. The 2 Be stars where a spectrum was obtained in H-alpha region and high resolution are: tet CrB and nu Cyg.
comet and spectroscopic observations on 22 may
nights are getting very short and I could only start observations of comets and spectroscopy of Be stars around 11pm. Comets I observed are: 29P, C/2023 A3, C/2023 H5. The nearly full moon is quite disturbing especially with the humid air. Spectra that could be obtained in H-alpha region and high resolution (R~~15000) are: omi Hercules and HD 175863. (data can be found in the BeSS database)
spectroscopi observations on 20 may
rather poor conditions for observing comets, so I decided to do only spectroscopy and was only able to record 1 spectrum of Be-star V521 Lyr in high resolution and H-alpha region
comet and spectroscopic observations on 13 may
after the clouds disappeared it cleared completely during the evening. I was able to start comet observations. comets observed are: 65P, 362P, C/2021 T4, C/2023 A3. Spectroscopic observations which also made of Be stars in H-alpha region in high resolution. stars from which a spectrum was obtained: HD 206773 and HD 203374.
comet and spectroscopic observations on 7 may
the evening began with clear skies. At this altitude, nights get very short and it does not get dark until around 22:30 local time. Unfortunately an hour later, clouds drifted in and it became completely cloudy. I had to suspend observations and close observatories. 2 comets I was able to observe:= 29P and C/2023 A3. With 2-the observatory I could obtain 1 spectra in high-resolution in H-alpha region: HD175511
comet and Spectroscopic observations on 3 may
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.
