This is a coupla days old. I'll bring it here even so.
There are currently two bright comets listed on my favorite visual astronomy site, heavens-above dot com.
The first is Comet 41P Tuttle-Giacobini-Kresak, currently very near Vega. It is a short-period comet with a moderately elliptical 6-year orbit. It is an intrinsically faint object, but it came very close to Earth a few days ago (perigee was April 26).
I managed to spot it in my 20x90 binoculars on the evening of the 27th, and I estimated its visual magnitude at about 10. Heavens-above gives its visual magnitude at 7.5 ... ten times as bright.
I remember hanging out on the Cloudy Nights site where visual astronomers congregate. Folks there would publish lists of "published v. perceived" visual magnitudes, and some discrepancies were large.
Some cool charts etc. are here:

The second comet is C/2015 V2 Johnson. This is a visitor from the far reaches of our Oort cloud (major axis is 120 thousand AU or two light-years, to the edge of what we call the Oort volume now) but during this pass, it got a tiny boost and is now on a hyperbolic (solar escape) trajectory. Again, Heavens-Above gives it a magnitude of 7.5 ... my estimate is about 9.0.
This visitor will be brightest in our skies in early June. I'll be watching it through my binos. It is near perihelion now, still outside Mars' orbit. I saw a prediction that it'll become naked-eye obvious at mag 2, but I doubt that very much now.
