comet observations on 1 march 2023

after a very nice day we had a clear but cold night as well. I could obtain some images of comets from my backyard observatory with my 0.4-m f/3.8 Orion Optics AG16 newton telescope: 29P, 118P, 119P, 180P, 452P, C/2020 S4, C/2022 A3, C/2022 E2, C/2022 E3

new comet C/2023 A3 on 1 march 2023

I observed comet C/2023 A3 with a remote Telescope.Live 0.61- f/6.5 reflector located in Rio Hurtado, Chile. This comet was assigned as comet C/2023 A3 (Tsuchinsan-ATLAS) via CBET 5228

comet and spectroscopic observations on 26 febr. 2023

a clear night with very good transparancy and low humidity. Perffect night to observe despite some disturbing moonlight. several comets could be observed: 29P, 118P, 119P, 211P, C/2020 S4, C/2022 A3, C/2023 B1. with the C11 and LHIRES III spectograph some spectra in high resolution could be obtained of H-alpha emission stars: V1165 Tau, PZ Gem, CQ Uma.

comet and spectroscopic observations on 13 febr.

following comets i was able to observe: 29P, 94P, 118P, 119P, 180P, C/2020 S4, C/2020 V2, C/2022 E3, P/2021 V2. also high resolution spectra could be obtainde from following Be-stars: PZ Gem, OT Gem, CQ Uma, HD 42477.

spectroscopic observations on 8 febr. 2023

again a clear and cold night (-3°C) and disturbing moonlight, i could obtain spectra of following Be-stars: PZ gem, HD 45314, 2 Ori, 25 Ori, 47 Ori.

comet and spectroscopic observations on 7 febr. 2023

during this cold and clear sky with disturbing moonlight, i could observe some comets and obtain some spectra of Be-stars. comets which could be observed are: 29P, 107P, 118P, 119P, C/2020 V2 (ZTF), C/2022 E3 (ZTF).

Be-stars where a spectra could be obtained are: AX mon, nu Gem, QQ Gem, V 715 Mon

spectroscopic observations on 6 febr. 2023.

a clear night with some clouds was a good opportunity to observe some Be-stars and obtain a high resolutions spectra in H-alpha region.$

of following Be-stars: 15 Mon, PZ Gem

new comet C/2023 B2 (ATLAS)

We observed an object mentioned on the PCCP with the Telescope.Live 0.61 f/6.7 Planewave telescope located in Riu Hurtado, Chile on 2 febr. 2023 and could confirm the cometary features of this object. Later on 7 febr. was this object assigned as comet C/2023 B2 (ATLAS) with CBET 5217

spectroscopic observations on 17 jan. 2023

the sky has low transparencies, but still managed to record 2 spectra. Spectra were obtained from the following Be stars: zeta Tau and HD 22780

new comets C/2022 W2 (ATLAS) and C/2022 W3 (LEONARD)

New comets where observed on 12 dec. and 26 dec. 2022 with my 0.4-m f/3.8 telescope, while these are still mentioned on the PCCP of the MPC. these objects where assigned as comet C/2022 W2 (ATLAS) via CBET 5203 and comet C/2022 W3 (LEONARD) via CBET 5204 both issued on Jan. 23 2022.
