Dynamical Properties Of Moving Magnetic Features Of Sunspots
Abstract
We have observed the active region NOAA 9662 on 16 and 17 October 2001 using the Advanced Stokes Polarimeter (ASP) at Richard B. Dunn Solar Telescope of National Solar Observatory. The ASP recorded all the full Stokes profiles in photospheric FeI 630.2 nm and Chromospheric Mgb2 517.2 nm lines simultaneously. During our observations, the active region was located near the center of solar disk. Combining the high resolution magnetograms obtained with the Michelson Doppler Imager on-board the Solar Heliospheric observatory; we determine the dynamical properties of moving magnetic features (MMF) around the prominent leading spots of the active region. In this paper we summarize the three dimensional structure of the MMFs and their photospheric and chromospheric dynamical properties.
