The most recent article on this I could find was Jan of last year and in it they said their research shows that it is still a ways off before it happens. There are some tale tale signs that a red giant goes through before it goes super nova and those signs take a few years to go through the cycle and Betelgeuse has yet to show any of those signs.
Unless there is a major catastrophe close to our solar system, anything that could happen to give us a "second sun" we will know about it years ahead of time, not months.
