SN 1994D was a Type Ia supernova event in the outskirts of galaxy NGC 4526.

It was offset by 9.0″ west and 7.8″ south of the galaxy center and positioned near a prominent dust lane.

[1] It was caused by the explosion of a white dwarf star composed of carbon and oxygen.

A possible detection of helium in the spectrum was made by W. P. S. Meikle and associates in 1996.
