The latest @AAVSO observations show that #Betelgeuse continues to decrease in luminosity in the visible. But in the #infrared (JH bands) its is constant. It could mean that a lot of dust (transparent in the #infrared) is forming and blocks a big part of the visible star light.

I very much believe in the dust formation scenario. What is the standard variation delta_JH expected for RSG? Usually variability amplitude is smaller at longer wavelength.
