Spectrophotometric observations were taken of the planetary nebula NGC 3918 at CASLEO. Spectra were obtained for the central 20'' using the REOSC spectrograph at low resolution (R 4100). Also, images were taken with different filters. This data was used to carry out a morphological study of the nebula. Results are consistent with the existence of a higher electronic density region at 10'' to the NW from the geometric center of the nebulae.
