As Shelton was among the first to report, he is credited as the discoverer, along with Oscar Duhalde and Albert Jones.
On February 24, 1987 at LCO, Ian Shelton and Oscar Duhalde became the first official observers of Supernova 1987A (SN 1987A).
Although small by modern standards, the Southern Observatory nevertheless became famous for its role in the discovery of SN 1987A when UofT astronomer Ian Shelton spotted the supernova while attempting to fix another disused telescope at the site.
