the evening began with high veil clouds, full moon and temperatures below 0°C. The cocktail of veil clouds and full moon made it difficult to observe comets. SQM was about 17.8 in zenith. comets that could be observed with my 0.4-m f/3.8 were: 43P, 333P, 487P, C/2017 K2, C/2021 S3, C/2022 E2, C/2022 N2, C/2023 Q1, C/2023 R1, C/2024 J2, C/2024 M1 and P/2023 S1. With the 2nd observatory – C11 telescope + LHiRes III spectrograph – some spectra around H-alpha region were obtained in high resolution. Be-stars where a spectra was captured were: gam Cas, PZ Gem, put Tau, 13 Tau, nu Gem.
spectroscopic and comet observations on 9 jan. 2025
a cold day, we had a clear sky here with some disturbing moon, I was able to start with spectroscopic observations of Be stars: gam Cas, HD224544 and PZ Gem (not observed), unfortunately the latter was interrupted by clouds that kept drifting in. I was also able to observe some comets after a series of technical problems: 333P, C/2021 S3 and C/2024 J2.
spectroscopic observations on 7 jan. 2025
In the late evening, the clouds slowly began to move away. I started late evening spectroscopic observation of PZ Gem and gam Cas in high resolution (r~15000) and was able to obtain good spectra.
spectroscopic observation on 3 jan. 2025
After a day of cloudiness and rain, it cleared up briefly in the early evening. I was just able to get a spectrum in high resolution of gam Cas. Afterwards, clouds kept drifting in and further observing was impossible.
spectroscopic observations on 23 dec. 2024
During a short clear sky, i could obtain 2 spectra of Be-Stars: PZ Gem and gam Cas.
comet and spectroscopic observations on 29 nov.
it was a clear night and i was able to observe several comets with my 0.4-m f/3.8 telescope. Comets that could be observed are: 43P, 117P, 130P, 328P, 487P, 493P, 496P, C/2021 S3, C/2022 N2, C/2023 A3, C/2023 Q1, C/2023 RN3, C/2024 M1, C/2024 N3, C/2024 N4. With the C11 telescope + LHiReSS III spectrograph i could obtain several spectra of Be-stars: V416 Aur, PZ Gem, psi Per, eps Cas, 11 Cam.
comet and spectroscopic observations on 28 nov.
After the clouds and the rain was gone, i could observe some comets: 43P, 130P, 493P, C/2021 S3, C/2022 N2, C/2023 A3, C/2024 M1, C/2024 N3. simultanously i could obtain, with the second observatory , several spectra of Be-stars: V801 Cas, gam Cas fot H-alpha and again gam Cas for the HeI-line, BK Cam.
spectroscopic observations on 25 nov.2024
During a short clear period, i could obtain a high resolution spectrum in H-alpha region of 48 Per. Then clouds drifted in again and I had to close the observatory
spectroscopi observations on 21 nov. 2024
a clear and cold night with some high clouds. I took this opportunity to obtain some spectra of gam Cas in H-alpha region (10x60sec) and He-I (7×600 sec) , HD 29866 (3x1200sec) and PZ Gem (8×1200 sec).
