The writer left out the constellation, a real no-no in good astronomy writing.
LOL, that was what I was looking for, and when I couldn’t find it, I assumed they included it in some kind of way that wasn’t obvious to me!
At the time of the photo, it was in Canes Venatici, the Hunting Dogs. Since then it has passed through several constellations. As I write it is in Ophiuschus, soon it will be in Serpens Cauda.
Best to check a finder chart on a night by night basis. Comets don’t stay put, that’s how Charles Messier used to tell if they were comets or something that belonged on his list of things that aren’t comets: If he looked back the next night and it wasn’t someplace else, it wasn’t a comet.
