They are eye-estimates of diameter based on a sequence of photographs in the collection of the UK Nova/Supernova Patrol. Taichi Kato, Japan has e-mailed details of a further independent discovery by Y.Fujita, Kuma-Kogen Observatory, Ehime, Japan. This was made on 1994 April 2.62UT using the 0.60-m f6 Ritchey- Chretien + CCD (unfiltered) when the estimated magnitude of the supernova was approximately 14.
