SN 1994DSN 1994D was a Type Ia supernova event on the outskirts of galaxy NGC 4526, which was observed in 1994.ObservationIt was offset by west and south of the galaxy center and positioned near a prominent dust lane. It was caused by the explosion of a white dwarf star composed of carbon and oxygen. This event was discovered on March 7, 1994 by R. R. Treffers and associates using the automated 30-inch telescope at Leuschner Observatory. It reached peak visual brightness, magnitude 11.9, two weeks later on March 22. Modelling of the light curve indicates the explosion would have been visible around March 3-4. A possible detection of helium in the spectrum was made by W. P. S. Meikle and associates in 1996. A mass of 0.014 to in helium would be needed to produce this feature.
