a short period of reasonable brightness had been announced. I took this opportunity to record 2 high resolution spectra of: HD 208682 and Kappa Draconis.
During this very clear evening with good transparency I observed some fainter Be stars: 11 Cam, HD 20566, HD 50658
The transparancy was not very well, but i could obtain 1 spectra of HD 112028 for H-alpha @6562.8 Å.
