a very clear and sky with good transparancy. I could observe some comets: 6P, C/2017 K2, C/2021 E3, spectroscopic observations are mad of some Be-stars: V2119 Cyg, QR Vul, 12 Vul
observation of new comet 15 july
While this object was still listed on the PCCP of the minorplanetcenter, I observed it with a remote 0.51-m f/6.7 telescope from Skygems in Namibia on 15 July. On 15 July, comet P/2021 N2 (Fuls) was assigned by CBET 5000 and M.P.E.C. 2021-N137.
comet and spectroscopic observations on 2 july
Observation conditions were not optimal, sometimes there were high clouds that drifted over. Some comets could be observed: C/2017 K2, C/2019 U5, C/2020 PV6, C/2020 T2. With C11 telescope and LHiRes spectrograph, I could obtain some Be-star spectrum: gam Cas for H-alpha detail @ 6562.8 Å, gam Cas for He-I detail @ 6678 Å, zet Oph, 28 Cyg.
new comet C/2021 L3 (BORISOV)
On 13 + 14 june, i could observe a possible new comet mentioned on the PPCP of the minorplanetcenter. This object was assigned as comet C/2021 L3 (BORISOV)
comet and spectroscopic observations on 13 june
during this clear night (twilight) i could observe several comets: 117P, C/2017 K2, C/2020 T2, C/2020 V2, C/2021 A1, C/2021 D2 and again a possible comet mentioned on the PCCP (found). WIth the C11 + LHiResIII spectrograph i could took a spectrum in high resolution of the H-alpha region of the nova V1405 Cas 2021 and the new nova Her 2021.
comet observations on 12 june
comet observation on 8 june
With remote telescope of Telescope.Live, i observed comet 7P on 8 june
comet and spectroscopic observations on 7 june
during this clear night (during twilight) i could observe some comets: 6P, C/2017 K2, C/2019 K7, C/2020 H6, C/2020 T2, C/2020 V2, C2021 A1. With the C11 + LHiResIII spectrograph, i could took spectra of gam Cas for H-alpha detail @ 6562.8 Å en gam Cas for HeI detail @ 6782 Å
comet and spectroscopic observations on 6 june.
Due to the astronomical twilight, I can only start with observations around midnight, and the nights are very short, With the 0.4-m f/3.8 newton telescope I could observe some comets, these are: 6P, C/2017 K2, C/2020 H6, C/2020 M5, C/2020 T2, C/2021 A1. With the C11 and LHiResIII spectrograph I obtain 1 spectra: HD 162428.
spectroscopic observations on 1 june
It is now the ‘grey nights’ here and it only gets reasonably dark at midnight. I was able to make spectroscopic observations of nova V1405 Cas 2021.
