DESCRIPTION:Speakers: Aneta Wisniewska (Leibniz Institute for Astrophysics
  Potsdam (AIP))\nObservational precursors of small-scale solar flares prov
 ide a basis information for future operational systems for large events fo
 recasting. We present the results of observational comparative study of th
 e active flaring (AFR) and non-flaring regions (ANFR). We study power spec
 tral density (PSD) of the intensity signal in the level of solar chromosph
 ere and corona\, through 2D-spatial maps of the power estimated for seven 
 active regions\, using intensity data from Atmospheric Imaging Assembly (A
 IA) on board Solar Dynamics Observatory (SDO). We selected six active regi
 ons with pore or sunspot feature\, and magnetic class of α\, β\, γ (acc
 ording to the Hale' magnetic classification system). The selected data are
  analysed in four wavelengths: 1700Å and 193Å\, 171Å\, and 131Å. This 
 very fast method of analysis based on 2D-Fourier Power Maps (FPM) and the 
 Wavelet Power Spectrum (WPS) of individual pixels spatially resolved in th
 e flare location.\n\nhttps://meetings.aip.de/event/24/contributions/335/
