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)
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 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)
comet and spectroscopic observations on 13 sept.
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.
spectroscopic observations on 12 sept.
I took a spectrum of gam Cas for HeI emission @ 6678 Å. with the C11 and LHiResIII in hijgh resolution.
spectroscopic and comet observations on 11 sept.
The sky has a very low transparancy, i started with comet C/2019 U6, bu i don’t saw the comet, due the very low transparancy en interupted the observatiosn for comets. I started with spectroscopic observations for gam Cas Hα and HeI @ 6678 Å. followed by 14 Lac, ups Cyg, omi And.
comet and spectroscopic observations on 6 sept.
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.
comet and spectroscopic observations
spectroscopic observations on 29 aug.
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.
spectroscopic observations on 28 aug.
After a rainy day the sky cleared in the late evening and I was able to record some spectra. spectra that i could obtain are: gam Cas for detail of the HeI @ 6678 Å and QR Vul, V442 And for the H-alpha detail.
spectroscopic observation on 21 aug.
after the clouds were gone, i could obtain a high resolution spectrum of gam Cas for HeI @ 6678 Å
