    This supernova occurred on Sunday, March 28, 1993, and was discovered by the Spanish amateur astronomer Francisco Garcia Diaz from Lugo (Spain). He discovered the supernova visually with his 10-inch Newtonian telescope at a magnification of 111, as an 11th magnitude star; it later reached a maximum brightness of about mag 10.5, around March 31, 1993.
