Chinesse did not call what we currently call supernova or supernovae but a "guest star" being it could be a comet or any other bright object in the sky. I know what you talk about the 600+day bright light in the sky but i thought the date was 1054. This as from what i understand was not...
Tycho Brahe observed the first supernova in 1572. My question is, did he name it. Everyone names the first new star or moon or whatever it be that they personally found. So did Brahe name his finding in the constellation Cassiopeia.
Thanks for you time
