The geomagnetic field varies in time and space, being a signal composed of periodic and non-periodic elements and is monitored in a triaxial system at observatories around the world. Based on data from INTERMAGNET observatories, we analyze the strongest storm of 2026, which occurred during January 19-21. The methodology used is spectral evaluation (Fourier, wavelet, signal decomposition into approximations and details with various functions on different levels, etc.). The wavelet technique allowed us to analyze th...
