The long term light curve is here: https://www.aavso.org/sites/default/fil ... lgeuse.jpg
This is not as deep as the dip in the 1940s, 1950s.

Re: Betelgeuse brightness
Nah, just a realist. I kinda figure it will be a spectacular show for a day or two, then we'll all be sick of it as it drowns out seeing anything else.bladekeeper wrote: ↑Tue Dec 10, 2019 1:27 am If the darn thing explodes, that will be classified as an astronomical event, and we all know how that turns out.

Or, most likely John will be right -

Stevenson's Extreme Explosions: Supernovae, Hypernovae, Magnetars, and Other Unusual Cosmic Blasts.
I'm currently reading his work on Star Clusters -The Complex Lives of Star Clusters. He covers a lot of variable star processes.
I've only been able to observe Betelguese naked eye so far & it is very noticeable. Had high thin clouds a few nights ago it should have "burned" through to be visible
& was not there as Rigel was. Clear tonight & it looks muted in both brightness & color to me, need to put the binos on it.
