Photometric observations of 804 Hispania performed at the Teide Observatory during the opposition in September 1998 are presented and analyzed. A rotation period of 7.405 ± 0.010 h was derived. It was possible to confirm that the lightcurve presents two maxima and minima. We discuss in detail some considerations on its nature.
