Comet Swan!!
Ok, went to the port, took the 20 x 80 binos, my camera (took some pictures but was unsuccessful)...
And I did finally and without doubt see the Comet Swan!!!!!!
Somewhere between Arcturus and the Big Dipper (actually above a line between Arcturus and Alkaid).
It's at 4:00 from a star called Seginus.
Thanks to Starry Night (The comet doesn't look at all like in this representation; it's more like a small cloud)
I saw it at 20:30 CET.
