The occultation of 16 Piscium by the asteroid 7 Iris on 2006 May 5 was observed with a mobile telescope at a site near Ithaca, New York. The signal from a video camera was time-stamped and recorded. Computer analysis of the recording shows a stepped disappearance and reappearance, as is expected for a double star. After correcting for saturated pixels in the recording, the two components of the double star were determined to have nearly equal magnitudes. By assuming a circular silhouette for the asteroid, the separation and position angle of the double star is constrained to two possibilities. This occultation result confirms a previous spectroscopic observation by G. Cayrel de Strobel.
