We present the results of the differential V light curve analysis of NN Del. We show
that NN Del is an EA eclipsing binary system with a period of 99.27 days and a highly eccentric
orbit. Photometric solutions obtained using the Russell and the Wilson-Devinney models seem to
indicate that both components are very similar in radii and luminosities (assuming a F5 spectral
type). Constraints imposed on the V luminosity of the system by the HIPPARCOS data suggest that
the components of the system could be subgiants instead of main sequence stars.^^^^
