INTRODUCTION In the last decade with the increase of time resolution in observational equipments, solar radio fast time structures were discovered at meter, decimeter, centimeter and millimeter wavebands. This has let to a surge of discussions about the mechanisms producing fast fine structures. However, the observed phenomenon of switch-type fast active groups coexisting with a loop prominence is for the first time in this field, this note mainly intends to describe the morphology and characteristics of the interesting event we observed on August 17, 1989 and to present the parameters about the rate of spikes and duration of indi-展开更多
