The star is indeed about +4.4 but appears very reddish like Betelgeuse.
Probably due to the dust cloud like the Sun is now around Sydney in the smoke cloud.

It would be nice that it brightens up to mag 0 in the upcoming decades, like in 1843, but that is unlikely.


The star is much hotter and has a luminosity of 5 million times the Sun according to the largest online astronomy textbook.

When unobscured, it should be mag -0.3 seen from here at 7500 light years, slightly brighter than Alpha Centauri. So it is darkened almost 100 times.
