@cosmos4u I implemented longer term daily binned visual AAVSO data with correct error bars (by the sqrt of n_obs)

Am I right that a 0.1 mag drop is around 25% less bright?pic.twitter.com/xt0xQzPy73

0.1mag is about 10% in brightness

Non-astronomer here: is there any other reasonable explanation for its dimming other than supernova or is it more or less a forgone conclusion that this thing is exploding in the near future?
-
Also, define "near future." In stellar terms, yes, Betelgeuse will explode in the near future. In that same framework, you and I are already dead, and every present-day nation on Earth has already been forgotten. Sometime in the next 100K years, I'm given to understand.

My ignorance curiosity : why does the relative error go quickly down at a certain point? Or is it just spread? Anyway same question...why?
-
The remark above about sqrt(n_obs) is your answer. More observations means less error in the average. And with the odd behavior, scientists are measuring this more frequently now.

Again, I ask, is anybody doing a nightly spectrographic analysis and where can I see the results?
