Hello Conference People I was wondering if any of you could bring a good photometer with you to the conference. On tour at Kitt Peak, I'd like to take lumens measurements of the full sun and the penumbral and umbral regions of the sundial's shadow edge. Fred and I are working on neat experiment we'd like to conduct with the group, but we need a photometer.
