During this evening with clear sky, but very bad seeing and low transparancy i took some comets: 29P, 48P (not detected) , 114P, 174P(dubious), 260P, C/2017 T2, C/2018 N2, C/2019 T3 and again the PPCP object A10iY9L. With the C11 + LHiResIII spectrograph i took spectra of following stars: Pleione, V357 Lac, VV Cep, HD 42477, HD 29866, HD 21650, 43 Ori.
spectroscopic observations on 29 dec.
During a short period of clear sky, i took spectra of Pleione and again PZ Gem (HD 45314) because of a different behaviour compared to the last spectra in the BeSS database, as a confirmation.
comet and spectroscopic observations on 28 dec.
Not a very clear night, some high cirrusclouds and low transparancy. So i decided to observe only some more bright comets, some weak comets are not very well captured. comets i observed this evening are: 29P/S-W, 76P, 114P, 260P, C/2017 T2, C/2018 N2.. With BRIXIIS-II observatory, i took HR spectra (H-alpha region) with the C11 + LHiResIII with 2400 l/mm grating of some Be-stars: PZ Gem, psi Per, phi Per, Pleione, Menkib, HD 37967.
comet and spectroscopic observations on 25 dec.
It was a while agoo that there was a clear evening. I started with a short list of comet and an object mentioned on the PCCP. observations where made of: 29P, 260P, 114P, C/2017 T2 and C/2018 N2. Object on the PCCP was A10iY9L (and could be detected). with the C11 and LHiResIII spectrograph are several Be-stars observed: Pleione, V422 And, bet Cmi, 69 Ori, 18 Gem.
spectroscopic observations on 23 dec.
remote observations of PCCP object on 23 dec.
In colaboration with F.-J. Hambsch, we observed object 10iMHA, mentioned on the PCCP as a possible comet. We could detect this object of about magnitude 18.0 with the 0.4-m f/6.8 ODK telescope in San Pedro de Atacama in Chile (observatory G39)
remote observations of a PCCP object on 22 dec.
I saw the object A10iAHM on the PCCP page and i observed this object with the remote telescope 0.61-m f/6.5 of Telescope.Live facility in Chile. Object is clearly a comet with a faint circular coma of about 1 arcmin. an animation can you find here
spectroscopic observations on 21 dec.
comet and spectroscopic observations on 20 dec.
after a rainy and cloudy day, the evening was promissing for a long clear sky. I could start with comet observations of comet C/2018 N2 (ASASSN), unfortunately i must interrupt the observations due windghusts which disturbed the observations a lot (roll-off observatory). With the dome and C11 + LHiRessIII i could observed several Be-stars and stars to obtain high resolutions psectra around the H-alpha wavelength. stars which are observed are: Pleione, zet Tauri, V801 Cas, 120 Tauri, 69 Ori, 28 Ori, 25 Ori, VV Cep.
