Temporal series of quiet region images near the center of the Sun are analysed. The images, monochromatic and in white light, have been acquired at the French-Italian solar telescope THEMIS (Tenerife, Canarie, Spain) by the Italian panoramic monochromator IPM. Solar granules evolution and the physical properties of the penetration convective photospheric region are discussed analysing velocity and intensity fields at the center of spectral lines. The observed lines are: C 5380, Fe 5379 and Fe 5576, which represent respectively the low, medium and high solar photosphere.

Abstract
Temporal series of quiet region images near the center of the Sun are analysed. The images, monochromatic and in white light, have been acquired at the French-Italian solar telescope THEMIS (Tenerife, Canarie, Spain) by the Italian panoramic monochromator IPM. Solar granules evolution and the physical properties of the penetration convective photospheric region are discussed analysing velocity and intensity fields at the center of spectral lines. The observed lines are: C 5380, Fe 5379 and Fe 5576, which represent respectively the low, medium and high solar photosphere.File in questo prodotto:
