Scientific paper

The RHESSI radius observations, made with its Solar Aspect Sensor (SAS), are providing our best characterization of the shape of the Sun. In spite of the differential nature of our measurement, which somewhat resembles that of Dicke's original (ground-based) Solar Oblateness Telescope, we still have a sensitivity in the radius measure to the presence of faculae and other small-scale magnetic features in the solar atmosphere. We find an clear positive correlation between radius and EUV brightness, as obtained from SOHO/EIT images; in addition we clearly see the Wilson Depression as a negative correlation. The facular correlation has been successfully used to screen RHESSI data from our initial study interval in 2004. We describe the nature of the correlation and discuss its interpretation.
