    The supernova happened long ago of course, but as far as I know it is the first time the visibility for us is predicted in advance: the host galaxy is at a redshift of 1.49, and due to gravitational lensing we see multiple images with a significant time delay between them. I don't understand the labeling system of the team (see reference below), but they saw the supernova in at least one of the images, another image probably had the supernova 50 years ago, and another image should get it within the next decade.
