comet and spectroscopic observation on 17/18 june

Due to the lattitude aand the summer, I can only start observations quite late. It only gets reasonably dark around midnight and the sun does not go lower then 15° below the horizon. transparancy is very poor and the moon unfortunately interferes too. I was able to observe a few comets: C/2017 K2, C/2020 K1, C/2020 U5 (not detected), C/2022 E3 and an object mentioned on the PCCP as possible comet. With the C11 and LHiRes-III spectrograph I was able to record spectra of iot Lyr and QR Vul, this for the purpose of spectroscopy opportunity for Be stars w/ TESS space photometry + CHARA interferometry, a ground based observing project with Jonathan Labadie-Bartz
