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.
new comet C/2021 T2 (LEMMON) on 7 oct and 8 oct.
while an object C60E7J2 mentioned on the PCCP could be observed on 7 oct. with my 0.4-m f/3.8 telescope in my backyard. Also we ( E. Bryssinck, M. Rocchetto, E. Guido, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori ) observed this object with a Telescope.live 0.7-m f/8 Ritchey-chretien (Z08) on 8 oct. Later on 8 oct. was this object assigned as comet C/2021 T2 (FULS) via M.P.E.C. 2021-T169
comet and spectroscopic observations on 7 oct.
During this clear evening with reasonable transparency, I was able to observe a few comets with the Orion Optics 0.4-m f/3.8 telescope: 29P, 107P, 186P, 431P, C/2017 K2, C/2019 U5, C/2020 PV6, C/2021 E3 and a possible comet, mentioned on the PCCP and could be detected. With the C11 + spectrograph LHiResIII, i ttok a spectrum of several stars for H-alpha detail: 13 Tau, 25 Peg, 31 Peg, bet Psc, kap Aql, pi Aqr.
milestone 500 observed comets and 1000 spectra of Be stars
I noticed that yesterday I observed my 500th comet since I started observing comets in 2005, a nice milestone, and I also passed the 1000 spectroscopic observations of Be stars, also a nice milestone
comet and spectroscopic observations on 4 oct.
After the clouds cleared I was able to observe some comets until the clouds reappeared. comets observed were: 132P, C/2017 K2, C/2019 T3, C/2017 B3, C/2020 S3, C/2021 R2 and an object C60DRY2 mentioned on the PCCP as possible comet and could be detected. Also simultaneously some spectra were recorded of: gam Cas for H-alpha detail, Gam Cas for HeI detail @6678Å, V442 And, HD189689.
new comet C/2021 S1 (ATLAS) on 29 sept.
A. Fitzsimmons reports the discovery of a comet in four 30-second survey images taken on Sep. 27 UT by ATLAS-HKO (T05), noting a condensed 9″ coma.
While this object was still mentioned on the PCCP, we could observe this object with the Telescope.Live 0.7-m f/8 Ritchey-Chretien in Oria, Spain, and confirm the cometary features of this object. Later was this object assigned as comet C/2016 S1 (ATLAS) via M.P.E.C. 2021-T21, issued on 2021 oct. 3th.
comet observations on 29 sept.
the weather was not so good because of clouds passing by. also i had to face some technical problems during the observations. I was able to observe a few comets though: 29P (in outburst), 193P, 324P, C/2019 T3, P/2015 T1 (431P) not found on the images)
