SN 1990U was a type Ic supernova event in the nucleus of the galaxy NGC 7479.

It was discovered July 27, 1990 by the Berkeley Automated Supernova Search after reaching magnitude 16±0.5.

[1] Initially this was classified as a Type Ib supernova, but the weakness of the neutral helium absorption lines led to a reclassification.
