On 20 September 2016, amateur astronomer Victor Buso from Rosario, Argentina was testing his telescope. When taking several photographs of galaxy NGC 613, Buso chanced upon a supernova that had just become visible on Earth. After examining the images, he contacted the Instituto de Astrofísica de La Plata. "It was the first time anyone had ever captured the initial moments of the 'shock breakout' from an optical supernova, one not associated with a gamma-ray or X-ray burst." The odds of capturing such an event were put between one in ten million to one in a hundred million, according to astronomer Melina Bersten from the Instituto de Astrofísica.
