comet and spectroscopic observations on 19 june.

the nights are now about the shortest of the year. It only gets really dark around 0:30UT. It was pretty much clear, with a cloud here and there. The 95% moon was interfering though, resulting in only an SQM in the zenith of 18.8. 2 comets: C/2019 T4 and C/2021 S3 were observed. 2 spectra of H-alpha region in high resolution, of Be stars: 58 Cyg and HD 208682 could be obtained.
