Apparently this gamma ray burst
https://en.wikipedia.org/wiki/GRB_080319B
was visible at around 5.2-2.5 magnitude to the naked eye in visible wavelengths despite being extrapolated to to 7.5 billion light years away through red shift measurements. That one star put out more like than a 1000 quasars or a 1000 trillion suns in its "afterglow" (for a minute) when it exploded?
Why this a star in particular and not some other stuff about a black hole colliding with an accretion disc. Spectra?
