Object name: NGC5403
NGC 5403 and its companion MCG +06-31-042 are a pair of galaxies about 130 million light years distant in the constellation of Canes Venatici. MCG +06-31-042 is listed at NED as simply a spiral galaxy though a note at NED calls it a "compact elliptical object". NGC 5403 is an edge on spiral that the NGC project classes simply as Sb but NED goes further saying it is a barred spiral with spectral lines SB(s)b: sp. The colon indicates some question about this classification. Being so edge on with heavy dust it's not surprising there's a disagreement here. It was discovered by William Herschel on May 16, 1787. It isn't in either H400 program.
