Here, as before, Starry Night greatly exaggerates the brightness of the comet, although the tail length is not much longer than the 2 degrees mentioned. ( You can use the celestial latitude marks at the very top for comparison. )
Note NGC 4697, which is a magnitude 11 object, per the Wiki link. In the photo it has a yellowish tint.
Note also that the photo shows many dimmer stars. So what I'm saying is, they're really hyping this thing. If it flairs into magnificence, as they're hoping for, I'll be pleased but very surprised. It just seems to me it's a physically small object.
Thanks dr_lew. I’ve been seeing what must be Jupiter more or less in the southern sky for the past week (that’s when I actually had a sky to see, the four month overcast has begun).
