Abstract
We are completing an experiment to measure the Newtonian constant of gravitation, G, with a suspended Fabry-Perot laser interferometer. The apparatus is operational and systematic errors have been found and eliminated. A result for G is hoped for in summer 2004 with an accuracy of roughly 30 ppm
