SN 1994I is a Type Ic supernova discovered on April 2, 1994 in the Whirlpool Galaxy by amateur astronomers Tim Puckett and Jerry Armstrong of the Atlanta Astronomy Club.

It was confirmed quickly by Michael Richmond and Alex Filippenko using the Berkeley Automated Imaging Telescope at Leuschner Observatory, who noted that SN 1994I was particularly blue.

High school students Heather Tartara and Melody Spence requested observations of the Whirlpool Galaxy on March 29 and 31, 1994.

Follow-up observations showed very weak helium absorption features, and thus SN 1994I seems to bridge the two classes, though it is still considered one of the best examples of a Type Ic supernova.

One suggests that the progenitors of Type Ib and Ic may be Wolf-Rayet stars, as they produce stellar winds that could blow away the hydrogen.
