The global long term periodic oscillations of the Sun are investigated on the base of three independent sets of data: 1.Records of Total Solar Irradiance (TSI).2.The average brightness of the solar photosphere in MDI (SOHO) and HMI (SDO) images.3.Records of the time variations of sunlight reflected from the planets during their passage in the field of view of the LASCO C3 coronagraph. It is found that in the low-frequency spectrum of global solar oscillations, there are modes with periods of 8–10, 36–38 hours and the main stable prominent mode with a period of ∼9-days.
