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.

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.File in questo prodotto:
