spectroscopic observations on 22 sept.
there were clouds that are coming over and high clouds are disturbing, so i decided to skip the comet observations and only try to take some spectra of stars: gam Cas (HeI @6678 Å), V2119 … Read more

spectroscopic observations on 17 sept.
Due to too much wind I could unfortunately not start observations of comets. I can, however, use the C11 and LHiRes-III for high resolution spectroscopy. This setup is in a dome and therefore more resistant … Read more
comet and spectroscopic observations on 16 sept.
It turns out to be a good night for sightings, although there are sometimes veiled clouds. I started observing comets but after 5 comets I had to interrupt the observations because of clouds and gusts … Read more
new comet C/2020 R4 (ATLAS) on 16 sept.
an object mentioned on the PCCP was observed with the 0.7-m f/8 Ritchey Chrétien of the TelescopeLive network in Almeria, Spain (MPC Z08) while this object was still mentioned on the PCCP. We could confirm … Read more
comet and spectroscopic observations on 14 sept.
Observation conditions are not so good, there are regularly high clouds, just after midnight I had to interrupt the observations because of too much cloud cover. According to the comets, I have been able to … Read more
