observations of a possible comet, mentioned on the PCCP could be observed and detected, later was this possible comet assigned as comet C/2021 Q3 (ATLAS). Observations with a Telescope.Live 0.7-m f/8 Ritchey-Chrétien in Oria, Spain
The observing conditions were not good, overcast clouds disturbed the sky so that the faint comets were difficult to detect. comets that are observed are: 69 (not detected), 255P (not detected), 382P (not detected), C/2017 … Read more
Tonight I welcomed G. De Cock during the observations, Geert was the founder of Antares amateur astronomy association where I joined in 1999 and where I gained my astronomy knowledge. I was able to observe … Read more
After the clouds had disappeared, I could start with observations. A few comets were observed + an object that might be a comet and is listed on the PCCP of minorplanetcenter. This object could be … Read more
An evening with periods of overcast, with the C11 + LHiResIII spectrograph I was able to capture a few spectra: RS Oph as a follow up to the nova outburst, HD 193182 and HD 192445.
during this evening with clear sky, i could capture some spectra: nova RS Oph, HD 206773
I received the atmospheric sensor and humidity sensor for the AAG cloudwatcher and mounted this sensor. Also i could see that the rain sensor was a little damaged and cleaned this sensor + i put … Read more
I observed a few comets between periods of cloud cover and overcast: C/2017 K2, C/2020 PV6. With the spectrograph I captured some spectra including nova RS Oph, 59 Cyg, gam Cas, V2136 Cyg.
i observed comet 67P/Gerasimenko-Churyumov with a remote 0.61-f/6.5 telescope from Telescope.Live network in Chile, used filter: SLOAN r’ photometric filter.
Between the showers there was a period of clearing and I took advantage of it to capture a spectrum of the nova outburst RS Oph with the LHiResIII and 2400 l/mm grating for H-alpha detail … Read more
