Supernova SN 1996ah was discovered in NGC 5640 on June 6, 1996 by J. Mueller, who was using the 1.2-m Oschin Schmidt telescope in the course of the second Palomar Sky Survey.[4]
SN 1996ah had magnitude about 18 and was located southwest of the centre of NGC 5640 (coordinates: RA 14h20m39.020s, DEC +80d07m21.00s, J2000.0).[4][1] It was classified as type Ia supernova.[1]
