Abstract
The case of a short-time ‘disappearance’ of the S-component source over the active region is described and its association with events in Hα is discussed. Under the assumption that in this case the radio source was observed to be covered by coronal mass ejection caused by filament eruption, estimates are made of the velocity of the ejection, its linear size and of the optical thickness.
