  • 05/12/2020

They had predicted a nice clear sky and it came true. SQM-zenit was 18.7. I could observe several comets: 11P, 29P, 36P, 141P, 156P, 173P, 391P (not detected), 397P, C/2019 L3, C/2019 T3, C/2019 Y5 (not detected), C/2020 M3, C/2020 N2. A number of Be-star spectra were also recorded, these are: gam Cas (HeI @ 6678Å), gam Cas (H-alpha), zet Tau, V442 And, HD 22780, 28 Ori, 25 Ori.
