Observations of scattering polarization and the Hanle effect in various spectral lines are increasingly used to complement traditional solar magnetic field determination techniques. One of the strongest scattering polarization signals in the photosph

The quantum theory of polarized light allows one to model scattering in the solar atmosphere for inferring its properties. This powerful approach has revealed two key long-standing problems in solar physics: the puzzling dilemmas between theory and o

We measure the resonance polarization in solar prominences in H α , H β and HeD 3 . A two-dimensional set-up with narrow-band filter, polarization analyzer and CCD camera is used to take prominence images in polarized light at high spatial resoluti

A fast flat‐fielding algorithm is presented that uses two orthogonal constant‐speed scans of an image across a detector to compute a flat field. Each scan image calibrates the cross‐scan direction of the other. Results from the ISOON solar tele

The features of the background magnetic field evolution, such as the dipole–quadrupole cycle, the four-sectoral structure of the magnetic field polarity migration, and the sectoral structure of the polar facular and active region concentrations (Mi

Using optically identical telescopes at different sites, we have measured the solar diameter with a drift-scan technique. In order to investigate the cause of the observed fluctuations, we not only compare observations made simultaneously by differen

A new type of two-dimensional polarimeter is used to measure the center-to-limb variation of the scattering induced polarization in a narrow continuum window up to the extreme limb. The polarimeter is set on the Tenerife Gregory Coudé telescope's ho
