abstract = "The models of VLF emission generation are based on cyclotron wave-particle interaction mechanism. According to such models the generation of waves is accompanied by a modification of particles pitch-angle distribution, that can lead to their precipitation in a loss cone. The dissipation of energetic particles in the atmosphere is accompanied by excitation of auroral emissions at altitudes of 100-200 km, that is observed by optical instruments. If the precipitated particles are rather energetic to penetrate at altitudes below than 90 km, the ionization by them of atmospheric gases leads to an absorption of radiowaves, that is observed by riometers. However, to find direct correlation between VLF waves and particles precipitation is complicatedly. Only a few papers with examples of such correlation are known. In this report we consider simultaneous morning time observations of VLF antenna, IRIS riometer array, and TV all-sky camera located at Kilpisj{\"a}rvi and Porojarvi, Finland. We used the continuous wavelet transformation of original data sets to find similarities in variations seen at time scales from 1 to 100 seconds.",
