the sky is not so transparent because of high veil clouds. I made no comet observations, but was able to obtain some spectra of Be stars until the sky closed completely due to drifting clouds. Be stars I was able to obtain a spectrum from are: gam Cas and PZ Gem

Finally another clear but cold night. Following comets were observed with my comet setup. 29P , 195P, 472P, C/2022 E2, C/2022 N2, C/2022 QE78, C/2024 M1, P/2015 CD60 and an object listed on the Minor-Planet Centre’s PCCP page could be detected. However, the quality of the image was insufficient to accurately measure any comet features. The astrometric data were, however, transmitted to the MPC. With my 2nd observatory I was able to obtain some high-resolution spectra around H-alpha area of following Be stars: gam Cas, OT Gem, AX Mon and PZ Gem and are freely available there for anyone who wishes to do so on the BeSS database.

It was cloudy and gray all day and towards evening there were some clearings however with high clouds that brought down the transparency. Still i was able to observe some comets, albeit in very poor conditions. Comets I was able to observe were: 496P, C/2017 K2, C/2022 E2, C/2022 QE87, C/2023 X2 and C/2024 M1, then the clouds became denser and I had to stop the observations. Also with 2nd observatory I was able to obtain some spectra of Be stars: gam Cas (10 x 60sec), PZ Gem (8 x 1200 sec) and HD 22780 (3 x 1200 sec).
comet and spectroscopic observations on 13 jan. 2025
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, zet 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.
comet and spectroscopic observations on 30 jan. 2025
finally another clear night, but cold. temperatures below zero. Comets that could be observed with my comet-setup were: 29P, 195P, 472P, C/2022 E2, C/2022 N2, C/2022 QE78, C/2024 M1, P/2015 CD60 and an object listed on the Minor Planet Center’s PCCP page. This very faint object could also be detected. The image was of insufficient quality to identify possible comet features, but astrometry was submitted to the MPC. With my 2nd observatory I was able to record some high-resolution spectra around H-alpha region of following Be stars: gam Cas, OT Gem, AX Mon and PZ Gem. All the data were submitted to the BeSS-database and are freely available there for anyone who wishes to do so.
spectroscopic observations on 23 dec. 2024
During a short clear sky, i could obtain 2 spectra of Be-Stars: PZ Gem and gam Cas.
