The C-Band All-Sky Survey (C-BASS) is a 5 GHz radio survey at 45 arcminute resolution in total intensity and polarisation. C-BASS provides a unique view of the Galactic synchrotron emission, which will be crucial for the success of future CMB missions such as Litebird and Simons Observatory, as well as for understanding astrophysical phenomena such as the Galactic magnetic field. Due to its unique frequency regime, C-BASS polarised data is predominantly dominated by polarised synchrotron radiation, which makes it an excellent data set for Galactic magnetic field modelling. I will be focusing on the previously unobserved new features in the polarised intensity morphology and how the data set compares with the current Galactic magnetic field models.
