Yes, getting brighter. That's too bad--I was really hoping that she'd blow. That would have been a fantastic sight!

Mystery solved, apparently it was a dust cloud...  :(

Astronomers say they've put to bed the mystery of why one of the most familiar stars in the night sky suddenly dimmed just over a year ago.

Betelgeuse, a red supergiant in the constellation of Orion, abruptly darkened in late 2019, early 2020.

The behaviour led many to speculate that it might be about to explode.

But a team using the Very Large Telescope (VLT) in Chile say the cause was almost certainly a giant dust cloud between us and the star.

how much of a electromagnetic disturbance would that star cause?

Not much.  It is about 500-600 light years away, and its axis is not pointed at us.  it would be bright for months, for sure, and might be detectable by some instruments other than optical telescopes.
