TL;DR: In this paper, the authors analyzed the magnetic configurations of three super active regions, NOAA 10484, 10486 and 10488, observed by the Huairou Multi-Channel Solar Tele-scope (MCST) from 2003 October 18 to November 4.

TL;DR: In this article, Zhao and Kosovichev found that magnetic flux tubes interact with large-scale vortical motions of plasma and the magnetic free energy is released to drive the plasma to rotate in two opposite directions, e.g., in the depth ranges of 0-3(5) and 9-12 Mm.

TL;DR: In this paper, a single wavelength position of the Fe I 5324.179 angstrom spectral line was used to calibrate vector magnetic fields, in order to complement the linear calibration at one wavelength position.

TL;DR: In this article, a possible correlation between the magnetic and velocity fields has been analyzed based on the SOHO/MDI magnetograms and Dopplergrams, and it is found that the observed large-scale weak magnetic field (weaker than 50 G (gauss)) is correlated with the velocity statistically.

TL;DR: In this article, the authors constructed a centennial data set that covers the H$\alpha$ data from five observatories around the world, which includes seven types of data products and eight types of feature parameters with which they can implement the functions of data searching and statistical analyses.
