    We present a catalogue of morphologically classified bright galaxies in the north equatorial stripe (230 deg\(^2\)) derived from the Third Data Release of the Sloan Digital Sky Survey (SDSS). Morphological classification is performed by visual inspection of images in the \(g\) band. The catalogue contains 2253 galaxies complete to a magnitude limit of \(r=16\) after Galactic extinction correction, selected from 2658 objects that are judged as extended in the photometric catalogue in the same magnitude limit. 1866 galaxies in our catalogue have spectroscopic information. A brief statistical analysis is presented for the frequency of morphological types and mean colours in the catalogue. A visual inspection of the images reveals that the rate of interacting galaxies in the local Universe is approximately 1.5% in the \(r\le16\) sample. A verification is made for the photometric catalogue generated by the SDSS, especially as to its bright end completeness.
