Assuming it goes in our lifetimes, how bright can we expect it to be early on?

Ten years ago,
>In July 2009, images released by the European Southern Observatory, taken by the ground-based Very Large Telescope Interferometer (VLTI), showed a vast plume of gas extending 30 AU from the star into the surrounding atmosphere.[16] This mass ejection was equal to the distance between the Sun and Neptune and is one of multiple events occurring in Betelgeuse's surrounding atmosphere. Astronomers have identified at least six shells surrounding Betelgeuse. Solving the mystery of mass loss in the late stages of a star's evolution may reveal those factors that precipitate the explosive deaths of these stellar giants.[50]

Now,
>In December 2019, astronomers reported that the star's brightness had significantly decreased and that it may therefore be in the last stages of its evolution.[57][58][59]

>will be bright enough to be visible during in broad daylight
>may be bright enough to cast shadows at night
If by "brighter" and "bright enough" you mean "dimmer" and "less visible" then yes.

I think it was a pair of stars they were thinking were about to collide. Further measurements since showed they were going to miss by a wide margin, unfortunately.

there isn't any supernova candidate close enough to actually kill us, and in a reasonable timeframe of human civilization nothing will wander in closer, a possible but unlikely exception being the pole of a star further out being exactly aimed at us and intensifying the result dramatically

im sure it would look very pretty if something like betelgeuse blew though

probably the latter, the final stages happen stupidly fast

This is actually a rather interesting phenomenon. I remember reading somewhere that ancient myths and legends spoke of Orion losing his shoulder. This event apparently happened repeatedly throughout history. The current dimming is likely just a repeat of that event and nothing to get excited about. Then again, who knows?
