The burst is related to the emission of coronal mass (CME), initiated by the lamp active area (N05E151). This burst was also observed by NDA radio telescope in the frequency strip of 30-60 MHz. We conclude that radio emission can emerge from the center of the CME core at a frequency of 60 MHz and exits the periphery of the core at a frequency of 30 MHz, which is caused by the solar crown at the appropriate frequencies. The results of the cross-correlation analysis of S-bursts associated with IOs using several radio telescopes on effective base lines up to 8950 km were given. These are LWA1 in the United States, NDA in France and three large radio telescopes in Ukraine - UTR-2, URAN-2, URAN-3. During the years since the research has passed, the staff of the low -frequency radio astronomy of the NAS of Ukraine, with the participation of the Laboratory of Decameter PGOs of the NAS of Ukraine, received a number of new topical results that display Ukraine in the cohort of the world centers of interplanetary research.
