spectroscopic observation on 2 aug.

Some high clouds and almost full moon limited me to take only 1 spectrum of gam Cas for the HeI detail @ 6678 Å in high resolution.

spectroscopic observations on 1 aug.

2 spectra could be obtained: gam Cas for the detail of the HeI emission @ 6678 Å and QR Vul for the H-alpha detail, both in high resolution (R=15000)

New comet C/2020 O1 (Lemmon-PANSTARRS), observed on 28 july

with remote telescope 0.61- f/6.5 from Telescope.Live in Tio Hurtardo, Chile we have observed a new object as possible comet on 28 july. Later was this object assigned as comet C/2020 O1 (Lemmon-PANSTARRS). This object is an active asteroïd of the main belt. Observations made by the comet research team of Telescope.Live: E. Bryssinck, M. Rocchetto, E. Guido, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori

comet and spectroscopic observations on 30 july

During this warm evening and very clear night with good transparancy but disturbing moon, i could obtain observations of a lot of comets: 29P (in outburst), 115P, C/2017 B3, C/2017 K2, C/2017 Y2, C/2018 N2, C/2019 K7, C/2019 T2, C/2019 T3, C/2019 U6, C/2020 F3, C/2020 K3, C/2020 K8, C/2020 M5, P/2019 LD2. With the C11 and LHiResIII , i could obtain 3 high resolution spectra of gam Cas, HD 4180, QR Vul.

spectroscopic observation on 29 july

some high clouds are present, comet observations are not such a good idea especially the cocktail of high clouds and disturbing moon (> 50%). I could obtain a spectra of gam cas with detail of the HeI emission @ 6679 Å

comet and spectroscopic observations on 22 july

an evening with some high clouds, but i could start with observing of some comets: C/2020 F3 (NEOWISE), C/2019 N1 (ATLAS), C/2017 Y2 (PANSTARRS), after these 3 comets i must interrupt the observations because clouds where coming in. With the C11 and LHiResII i could obtain a high resolution spectrum of HeI @ 6678 Å of gam Cas, and the Sodium doublet of comet C/2020 F3 (NEOWISE)

comet and spectroscopic observations on 21 july.

looks e very clear night and i could observe several comets with the 0.4-m f/3.8 Newton telescope: 115P, 257P, C/2016 Q2, C/2017 K2, C/2017 T2, C/2018 U1, C/2020 F3. With the C11 and LHiResIII i could obtain several spectra of Be-stars: 31 Peg, 25 Cyg, 28 Cyg, QR Vul.

comet and spectroscopic observations on 20 july.

after several nights of clouds i could observe again. I started simultanously with comets and spectroscopic observations: comets which are observed are: 115P, 257P, C/2017 T2, C/2018 N2, C/2019 K7, C/2020 F3 (NEOWISE), C/2020 H4 (LEONARD) – not detected, C/2020 K3 (LEONARD), C/2020 M5. With the C11 and LHiResIII i could obtazin several high resolution spectro of the H-Alpha detail of stars: 66 Oph, phi Per, kap Aql, phi And.
