Solar physics at Nançay radio observatory: Recent developments

The Nançay station of Paris Observatory operates two key instruments for solar physics: the Decametre Array (dynamic spectra of bursts, 20-70 MHz) and the Radioheliograph (images in the 150-450 MHz range). A new spectrograph (130-1000 MHz) is under construction for scientific and space weather purposes. This contribution summarises the performances of the instruments and illustrates recent results on the quiet Sun, quasi-continuous particle acceleration in active regions (noise storms) and radio observations relevant to coronal mass ejections and solar energetic particle events. These observations will be an essential support in future investigations of the Sun-Heliosphere connection with Solar Orbiter and Solar Probe.
