update: With all the newest news about including what the Dr. Becky video discusses as linked in How do magnetic fields mess with astronomers' observations? I'll bet this question can now be answered!


The Astronomers Telegrams #13341 The Fainting of the Nearby Red Supergiant Betelgeuse and #13365 Updates on the “Fainting” of Betelgeuse (both in December 2019) discuss the importance of measuring color temperature and spectral features of the needed observations.

So far, does the current Did the recent fainting episode show the same kinds of spectral changes behavior as the irregular but more limited variation in brightness, or does did it contain a dimming component that affects it differently, for example as intervening material (e.g. dust, debris, broken planets) might do?

Betelgeuse, Betelgeuse, Betelgeuse, there, I said it, now let's wait 700 years to see what happens.
