Currently it's about magnitude +10, which puts it just on the edge of visibility with standard 10x50 binos. It's supposed to reach about +2 or +3 when it blows, or around the same as Coronae Borealis' brightest star (give or take half a magnitude). So here it is now:

And here is with the "new" star, probably exaggerated in comparative brightness:

I have Stellarium mobile, which makes it pretty easy to find at night (when it's up), but the light pollution is getting pretty bad in my city these days.
You bet, that's why I said, "The star itself will look quite different given the fact the star has not even been visible to the
unaided eye." since the 1940s.
Btw, Stellarium is a nice program and I use similar platforms to control a telescope mount by simply clicking an object on the celestial map that I want to the scope to move to. Once everything aligned precisely, the object appears exactly in the cameras center of field of view.
