I'm sure other people noticed this but I'll point it out just to be on record. If it's ~10,000 lightyears from us then the supernova occured 10,300 years ago, we only got the update recently. Kinda ties back into the quantum mechanics stipulation that no information may be transmitted faster than the speed of light (including gravity waves, so even if we could have measured these more than 300 years ago they wouldn't change till the light reached us).
