摘要：
A comparative analysis of sunspot oscillations and related radio sources in the active regions AR 8949, AR 8951, and AR 8953 is carried out using SOHO MDI data and simultaneous observations with the Nobeyama Radioheliograph, with a one-minute time resolution on scales of tens to hundreds of minutes. The radio sources in the selected active regions are similar to 40 000-60 000 km away from the corresponding spots, with the periods of long-term oscillations of the radio sources being similar to 12% longer.
