Photo 1
Figure1: A 5x5 arcminute CCD image of the prototype gravity-mode pulsating subdwarf B star, PG1716+426, and nearby comparison stars. North is up and East is to the left. The subdwarf B star pulsator is the brightest star in the northeast quadrant. The image was taken through an R filter at the University of Arizona Mt. Bigelow 1.6 m telescope and is one of hundreds used to measure the light curve of the star.
