NGC 1892 is a spiral galaxy in the constellation Dorado. It was discovered November 30, 1834 by John Herschel. A probable supernova of type IIP was photographed by the Carnegie-Irvine Galaxy Survey (CGS) in 2004, but it was not noticed until Brazilian amateur astronomer Jorge Stockler de Moraes compared the CGS image to one he took in January 2017.
