摘要
We present radio images of the quiet Sun obtained with the Nancay Radioheliograph between 150 and 450 MHz, using the latest improvements in the instrument and in the data processing techniques. We emphasize new aspects of the corona observable in this frequency range, particularly the prominence of coronal holes, and discuss implications for future studies.
