| Comment | The sky was "so so" near the horizon but I think I saw the comet. My lattitude is 43°N. That was not possible with a standard 7x50 bino because of this very brillant moon. But two times (2 or 3 seconds maximum) during my 30 minutes session with my Vixen 25x126 bino I was able to detect a diffuse cloud of +/- 60' on the same place, so maybe that was our comet ??? If yes, the magnitude was around 5 (difficult to be sure).
Impossible to sketch anything with this white sky. Maybe tomorrow ?
