On 23 February 1987, Ian Shelton took a photograph the Large Magellanic Cloud at the Las Campanas Observatory in Chile. When he developed it he noticed a bright star where there wasn't one before. He immediately told his colleagues and within hours news of the discovery of a supernova (SN) went round the world. Since it was the first one discovered that year it was labelled 1987A.
