comet and spectroscopic observations on 28 nov.

Despite the high humidity and lunar phase of 0.98, I was able to observe some comets until suddenly a thick fog came up. Comets that were observed: 29P, C/2017 K2, C/2019 L3, C/2019 U6. With the C11 + LHiResIII spectrograph, i was able to record the following spectra: gam Cas (HeI), gam Cas (H-alpha), HD 217050, lam Cyg.
