Variations of the coronal temperature measured with the SWICS instrument on board ESA-NASA’s Ulysses from December 1990 to January 2007. Solar wind flow from coronal holes is characterized by high solar wind speed (700-800 kilometres per second) and low coronal temperature (1 – 1.3 million Kelvin).
