A new BAA VSS visual chart for Betelgeuse has been prepared by John Toone and is available in the original article on the fading of this star. Unusually, this is an 80 degree chart, which includes many of the bright stars in the winter sky. You can also download the chart directly from the VSS website.
The latest observation in the BAA VSS database has the star a mag 1.6 (Gary Poyner, Jan 28, visual).
Further observations are encouraged to see whether the fade is actually bottoming out.
