comet and spectroscopic observations on 28 nov.

After long weeks of clouds and lots of rain, we had a beautiful clear day finally . In the evening I was still able to observe comet 12P/PONS-BROOKS and take a high resolution spectrum (of the H-alpha region) of a Be star omi Aqr. After about 1 hour unfortunately clouds came up again and I had to close the observatories. (Due to the lack of suitable reference stars in the FOV, I could not determine an Af(rho) parameter for comet 12P observation)
