On 3 March, I observed an object: A10GhLU, listed on the PCCP-page (possible comet confirmation page) of the MPC (minorplanetcenter), with my 0.4-m f/3.8 AG16 telescope in my backyard and was also able to confirm its cometary appearance and send a report to CBAT and MPC. Later, this object was assigned as comet C/2022 A3 (LEMMON-ATLAS) via CBET 5106 issued on 7 March 2022.
spectroscopic observation on 6 march
The clear nights follow each other nicely. With the C11 telescope + LHiress-III spectrograph, I capture a spectrum of Be-star: PZ Gem (3 hour observation) in high resolution (R > 15000)
comet and spectroscopic observations on 5 march
weatherconditions are very well, a little more humidity and lower transparancy. SQM about 18.7 … 18.8 in zenit. Several comets could be observed: 19P, 29P, 67P, 116P, 402P, C/2019 L3, C/2020 U4, C/2021 Y1. With the second observatory with C11 + LHiResIII spectrograph, i could obtain spectra of : nu Gem and PZ Gem.

comet and spectroscopic observations on 3 march
The weather conditions are excellent: no wind, clear night, no clouds, dry air… i observed several comets: 4P, 29P, 67P, 104P, C/ 2019 L3 and a possible comet mentioned on the PCCP (40 x 120 sec. hours observation). With the C11 + LHiRess spectrograph i could capture spectra of PZ Gem for 3 hours (9 x 1200 sec)
spectroscopic observation on 22 febr.
During a clear night (after 23u30 local time) i could open the observatory and obtain a high resolution spectrum of PZGem (total exposuretime was 140 min.)
spectroscopic observation on 14 febr.
During an almost clear period of 1 hour, i could obtain a spectrum of Be-star PZ Gem in high resolution with the C11 and LHiResIII spectrograph
spectroscopic observation on 12 febr.
with disturbing moonlight and high cloud i could obtain a spectrum , in high resolution and H-alpha region, of Be star: PZ Gem

spectroscopic observations on 4 febr. 2022
a high resolution could be obtained with C11 + LHiResIII spectrograph with the 2400 l/mm grating of Be star: PZ Gem
