Abstract: We have made preliminary measurements of the continuum intensity contrast associated with supergranular flows using data from the Precision Solar Photometric Telescope at the Mauna Loa Solar Observatory. Supergranular centers are about 0.4-0.6% dimmer in the red and blue continuum (6.5K cooler) than the mean photosphere. The role of network magnetic flux elements as well as the dynamical implication of these measurements are currently being examined.
