Abstract

Multiwavelength solar observations were carried out at the THEMIS telescope in order to investigate the propagation of the plasma jets during and after a flare occurrence. The data obtained in the Hα, Na I D2, and Fe I 557.6 nm lines show that the perturbations detected in the higher layers due to a B-class flare do penetrate down to the photosphere. The observational evidence of such perturbations is crucial for the identification of the source of the solar oscillations.
