Coordinated high-resolution XUV and centimetric observations of active regions obtained from Skylab and Stanford are compared with the aim of determining the nature of the centimetric radiation. It is concluded that the thermal gyroresonance process is the most likely emission mechanism for the bright compact radio sources associated with sunspots.
