Abstract We have studied the association between different aspects of the magnetic field behaviour in large active regions and the solar irradiance variations. It was found that irradiance decreases were accompanied by enhanced flare and coronal mass ejection activity. A still better association seems to exist with broadband, long-lasting noise storm activity. This indicates that the enhanced generation of weak MHD shock waves causing noise storm in large interconnecting coronal loops is related to the appearance of irradiance dips.
