| Resumo | Radio Noise Storms (RNS), also named as type I emissions, last from a few hours to several days. They are associated to the evolution of active regions (AR), as well as the occurrence of solar flares. However, recent studies show that RNS are not connect directly to flares, but mostly to reorganization of the magnetic fields of active regions. Considering that type I emissions is generated by the fundamental plasma emission, the reorganization of the scales in active region magnetic configuration was investigated as the possible process for maintenance of the RNS. On August 12, 2012, the BLEN7M (Switzerland) spectrograph of e-CALLISTO network, registered a RNS (14:08 - 15:35 UT); and the NOAA 11542 was in the centre of the solar disc, without the occurrence of intense flare (admitting only flares A and B Classes). The time evolution of the magnetic power spectra was used for identify in which length scales the reorganization of the photospheric magnetic fields occurs. The 481 line-ofsight (LOS) magnetograms recorded by HMI instrument (Helioseismic and Magnetic Imager) on board of the SDO (Solar Dynamics Observatory) were analysed to study the power spectra and the energy spectra. Here, we present the preliminar results of this analysis. The spectrum index, α;, was -2.29, greater than -5/3 (the Kolmogorovs index), indicating the possibility of energy transfer from small to large structures. Furthermore, increasing the value of the power law index causes a redistribution of energy along the power spectra. The reorganization of the photospheric magnetic fields occurred at values corresponding to scales greater than ∼ 20.9 Mm (∼ 0.03 Rs), above the photosphere, beginning soon after the beginning of RNS (∼ 10 min) and continuing after the end of that (∼ 1h30min.). The time evolution of the dissipation spectra revealed that the power increased before the starting of the RNS for a wide range of wave numbers. These results will be presented. | |||
