Two of the authors of the new #Betelgeuse paper strengthening the case for a companion star are #AmateurAstronomers: in https://www.aavso.org/blog/aavso-observations-help-confirm-betelgeuses-long-suspected-companion the #AAVSO explains how their precise photometry of the star contributed.

I have observed #TCrB around 30 nights during June&July each about 4 hours period with 22 second resolution. However, although there has been some possible findings of trends in my observations I have not actually analyzed those.
There are many research papers of these Cataclysmic Variables (CVs) published, and seems that in #TCrB there are brightness flickering even inside 1 minute. I have reported my observations to #AAVSO database, which researchers are using actively. -
P Cygni spectra comparison. Three moments of a very bright blue star surrounded by a high speed, expanding envelope.
Spectra produced with own data at the #AAVSO.

@thomasconnor Does that star have a name? Can it be seen with midrange amateur equipment, like 5-8" telescopes? What is its period? Might make for a fun #AmateurAstronomy project. #AAVSO
