Research Note The rotation period of 804 Hispania: Some considerations on its nature

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.
