Abstract
We present results from quiet sun observations in the metric range. Solar images where obtained through rotational aperture synthesis at a number of frequencies, using the Nancay radioheliograph in its latest version, from 2004 to 2011. The main morphology is described, and compared to the magnetic field topology. We also measured on-disk spectra, of the average sun and of coronal holes, and equatorial and polar limb profiles. From these measurements, simple temperature/density atmospheric models are derived and briefly discussed.
