Abstract

A study was made of the optical warps of NGC 5907, by means of CCD photometry, for theU andI filters, as well as for a narrow band filter centred at Hα. Our observations were extended out to about 380 arc sec in the NW side and out to about 348 arc sec in the SE side. The Hi warps begin at these galactocentric radii, so that the optical ones are not clearly distinguished. TheU warp is larger than theI one in the NW, but this difference is not appreciated in the SE. The disk shows slight corrugations.
