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
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
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.
a clear day and night after 2 weeks of cloudy and rain. i observed some comets: 29P (in outburst !), 61P, 127P, 179P, 408P, C/2020 V2, C/2021 Y1, C/2022 J2, C/2022 U2, C/2022 U3, P/2022 V1 and also an object mentioned on the PCCP as possible comet and could be detected and confirmed with cometary appearance. Simultanously i could also capture several high resolution spectra in H-alpha region, with my second observatory, of Be-stars: V439 Cep, PZ Gem, HD 208682, HD 50658, 6 Cep.
during this clear night and low temperatures (-5 °C) i could obtain several spectra of Be stars: 25 Peg, HD 32188, V357 Lac, V801 Cas.
a very cold night ( temp: – 4°C) but a clear night. some spectra could be obtained of Be-stars: 14 Lac, 16 Peg, HD 22298, PZ Gem.
this evening i could after some technical issues due the very high humidity (> 90% RH) starting with observing comets. Comets wich could be observed are: 22P, 61P, 196P, C/2020 F5, C/2021 T4, C/2021 Y1, P/2019 LD2 (not detected). simultanously, i could obtain some high resolution spectra of several Be-stars: 11 Cam, HD22780, HD 24479, PZ Gem, V422 And.
