(3200) Phaethon, 2017.12.16. 17:45-18:10 UT, Kerepes, 100/400T (Newton, Dobson), 50x (8 mm Planetary), detail drawing.

It was easy to find it using precise coordinates though it is not very bright. It is moving rather fast. I measured 39" / minute from my drawing. I estimated its brightness to be 11.0m at 17:57 UT and 10.9m at 18:10 UT. I felt that it was getting slightly brighter during the observation but this might be false. I used the stars TYC 1744 720 (11.3m) and TYC 1744 997 (10.4m) for the estimation. I didn't see its color. It would need to be much brighter to be colored in my little telescope.
I made the drawing during (3200) Phaethon's 2017 December close approach to Earth and a couple of days after the maximum of the Geminid meteor shower. Phaethon is the mother object of the Geminid meteors, a dead comet nucleus. I didn't see Geminids during the observation but a couple of days before we were lucky.
