With a remote 0.61-m f/6.5 telescope from Telescope.Live, comet 57P was observed. An outburst could be observed (sudden brightening of the comet).
spectroscopic observations on 17 oct.
spectroscopic observations on 16 oct.
comet and spectroscopic observations on 15 oct.
according to the weather forecast there would be a clear night, unfortunately clouds are coming in very regularly here. I also have to deal with reciprocal problems of momentary loss of USB connection to CCD/and fo focuser which causes constant interruption of observations. Attempts were made to observe several comets including: 132P, C/2017 K2, C/2020 K1, C/2020 PV6, C/2021 D2, C/2021 E3. With the C11 + LHiress III spectrograph, a high-resolution H-alpha detail spectrum was taken from several stars: HD 216057, HD 21620, HD 21455, 14 Lac.
spectroscopic observations on 12 oct.
during a short period of clear sky i could obtain spectra (H-alpha-detail in high resolution) of following stars: eps Cas, BK Cam.
spectroscopic observations on 11 oct.
spectroscopic observations on 9 oct.
spectra of H-alpha region could be obtained with the C11 + LHiResIII spectrograph of folowwing stars: 25 Cyg, 28 Cyg, HD 21362, HD 199128
comet and spectroscopic observations on 8 oct.
new comet C/2021 T1 (Lemmon) observed on 4 oct.
While this object was still mentioned on the PCCP, i observed this object with the Orion Optics AG16 0.4-m f/3.8 in my backyard. Later was this object assigned as comet C/2021 T1 (Lemmon) via CBET 5053 issued on oct. 8.
new comet C/2021 S3 (PANSTARRS) observed on 4 oct.
WHile an object was mentioned on the PCCP, i could boserve this object with a remote Telescope.Live 0.5-m f/3.6 telescope in Rio Hurtado, Chile on 4 oct. This object was later assigned as comet C/2021 S3 (PANSTARRS) via MPEC 2021-T166 issued on 8 act. 2021.
