Students in Optics, Leah Barner, Ray Rutkowski and Steve Wu, use the sky polarization apparatus described below. Finally a clear day arrives and they take their equipment up on the dike for an unobstructed view of the sky.
Tim Concoran continues to work on a light meter. He has finishes assembly of the current/voltage amplifier electronics. He has built a mount for a solar cell and built a device, which mounts on a telecsope stand, for used in studies of sky polarization. He has also built a mount for scanning diffraction patterns.

Justin Ogden works on a light meter. He prototypes the circuitry for a current to voltage amplifier. The amplifier works as a light meter when connected to a solar cell.
