How visible would this have been in the night sky?

As a starting point, the sun's absolute brightness is much higher than this star's, and this star supposedly came within .8 light years of us. That's 50,591 further than Earth is from the sun, which means it would be no brighter than most of the stars you see in the sky... unfortunate, huh :(

I meant "50,591 times further".

According to the paper, not at all, barring some nicely-pointed flare events. It's a very dim star.
