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.

Last night, prior to seeing this thread, I was viewing Betelgeuse through my binoculars, and thought, "gee it's looking kinda dim."

Re: Betelgeuse brightness
It's looking very faint here but the bushfire smoke is so thick I can barely see down the street so don't put too much on that observation.
Anyone with aDSLR and a 50mm lens could take pictures straight off a tripod, keep the exposure constant and short enough that you don't blow the well. You could do your own light curve-just for fun.

If the darn thing explodes, that will be classified as an astronomical event, and we all know how that turns out. We'll be clouded out until May at least...

I think this is simply a periodic dip, and probably nothing special. When it does go supernova, it will probably happen as the sun passes north of it .

Re: Betelgeuse brightness
It has always seemed dimmer to me but then again the color of it's light has always been kind of reddish and that does not show as good as bright whitish Blue like Sirius. Still would seriously mess up Orion Constellation if it went away.

Re: Betelgeuse brightness
Clear skies last night. Eyeball view, looked to be even dimmer than I recall from 12/9.
Dimmer than Aldebaran and Procyon. Comparable to Pollux.

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.
