several stars are observed with the LHiResIII spectrograph and 2400 l/mm grating. stars which are observed are: Castor, kap Dra, lam Eri, eps Cas, 15 Mon, 19 Mon
spectroscopic and comet observations on 26 febr. 2021
After solving many technical problems, I can now observe comets again as the first evening before 2021. Comets on the menu were (unfortunately due to the full moon): 9P (not detected), 29P, 156P, 409P, C/2020 T2, C/2020 V2, C/2021 A2, C/2021 A4. With the LHiResIII spectrograph a spectra of following stars was obtained: HD 70340, gam Cas, 25 Ori.
spectroscopic observations on 9 febr. 2021
After a full month of not being able to observe due to the persistent bad weather, I was finally able to open the observatory again, although in cold temperatures of -7° C. I was able to obtain some spectra with the LHiResIII spectrograph and took some stars for the TESS project (see ARAS forum). Stars I was able to capture a spectrum are: gam Cas (H-alpha region), gam Cas (HeI @ 6678 Å), 25 Ori, 15 Mon, HD 43285, ome Ori, OT Gem.
New comet C/2021 B2 (PANSTARRS) on 18 jan.
With a remote 0.61-m f/ 6.5 telescope of the Telescope Live network in Rio Hurtado, Chile i could detect and confirm the cometary nature of the new possible comet, mentioned on the PCCP on 18 jan. 2021. Later on 22 jan. 2021 this object was assigned as comet C/2021 B2 (PANSTARRS) via CBET 4921 and M.P.E.C. 2021-B120
New comet C/2021 A7 (NEOWISE)
In collaboration with F.-J. Hambsch we observed an object while it was still mentioned on the PCCP of the minorplanetcenter on 13 jan. 2021. We could detect this comet on the images taken with the 0.4-m f/6.8 ODK of F.-J. Hambsch his privat observatory (ROAD) in Chile (MPC:G39). Later on 15 jan. this cobject was assigned as comet C/2021 A7 (NEOWISE) via CBET 4917 and M.P.E.C. 2021-A211 : COMET C/2021 A7 (NEOWISE).
New comet C/2020 X4 (LEONARD)
on 15 dec. 2020, i observed a new object mentioned on the PCCP of the minorplanetcenter from my backyard with the 0.4-m f/3.8 newton telescope, later on 10 jan. was this object assigned as comet C/2020 X4 (LEONARD) via MPEC 2021-A101
New comet C/2021 A2 (NEOWISE)
I observed a new possible comet, mentioned on the PCCP of the minorplanetcenter on jan. 7 with a Telescope.Live refractor Takahashi FSQ-106ED from Heavens mirror observatory in YASS, Australia. This object was assigned as comet C/2021 A2 (NEOWISE) via CBET 4908 and MPC 2021-A100 on jan. 10.
spectroscopic observations 8 jan. 2021
Finally, a clear night for observation. Unfortunately, the ASA mount is still out of service due to the defective internal USB hub and completely dismantled. I was able to observe some spectra with the C11 and the LHiResIII spectrograph in high resolution. stars of which one spectra could be obtained are: zet Tau, ome Ori, 25 Ori, OT Gem, V715 Mon.
remote observations of PCCP object on 23 dec.
same object A10iMHA was observed, now in collaboration with F.-J. Hambsch his remote observatory in Chile (San Pedro de Atacama). Object could be easely detected.
spectroscopic observations on 20 dec.
I could obtain some high resolution spectra of the H-alpha region of Be stars: pi Aqr, bet Psc, 8 Lac.
