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 to gusts of wind. Stars that were observed are: gam Cas for HeI @ 6678Å, (as a test another nearby star was also taken for the instr. response), HD 24479, HD 4180, eps Cas.
It turns out to be a good night for sightings, although there are sometimes veiled clouds. I started observing comets but after 4 comets I had to interrupt the observations because of clouds and gusts of wind. comets that I could observe: A/2019 U5, C/2019 L3, C/2019 O3. Simultanously i started spectroscopic observations with C11 + LHiResIII for high resolution : gam Cas for HeI detail @ 6678Å, gam Cas for H-alpha detail, HD 21362, phi And.
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 the cometary appearance of this object and appears as central condensation with a small coma of about 8″ and some hint of a tail in p.a. of 310 degrees. Later this object was assigned as comet C/2020 R4 (ATLAS) via CBET issued on 16 sept. and MPEC S33: COMET C/2020 R4 (ATLAS)
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 observe: 257P, C/2017 Y2, C/2018 N2, C/2018 U1, C/2019 K7, C/2019 U6. At the same time, I was able to record some spectra with the C11 and LHIRESIII spectrograph: gam Cas for HeI emission @ 6678 Å, V442 And (H-alpha detail) , ALFIRK (H-alpha detail)
During this clear night with very good transparancy and weather is observed several comets: 11P, 29P, 215P, 257P, C/2016 Q2, C/2017 B3, C/2017 K2, C/2017 Y2, C/2018 N2, C/2018 U1, C/2019 K7, C/2019 O3, C/2019 T3, A/2019 U5, C/2019 U6, C/2020 N1, C/2020 Q1, P/2020 P2. With the C11 and LHiResIII spectrograph i could take spectra: gam Cas for HeI detail @ 6678 Å, gam Cas for H-alpha detail, QR Vul, HD 206773.
I took a spectrum of gam Cas for HeI emission @ 6678 Å. with the C11 and LHiResIII in hijgh resolution.
several faint comets are observed with the 0.4-m f/3.8 corrected newton (AG16 ORION OPTICS): 257P, C/2017 K2, A/2019 U5, C/2017 Y2, C/2018 N2, C/2019 T2, C/2019 U6, C/2019 LD2. With the C11 + LHiResIII spectrograph several high resolution spectra could be obtained: gam Cas (HeI @ 6678Å detail), tet CrB (H-alpha detail), 28 Cyg and HD 168957.
during a short period of clear sky, i could obtain 2 spectra: gam Cas for HeI detail @ 6678 Å and 1730 Vul for H-alpha detail.
