Full-disc observations of the Sun in the Ca ii K line provide one of the longest collections of solar data. First such observations were made in 1892 and since then various sites around the world have carried out regular observations, with Kodaikanal

Abstract Polarimetry is a crucial method to investigate solar magnetic fields. From the viewpoint of space weather, the magnetic field in solar filaments, which occasionally erupt and develop into interplanetary flux ropes, is of particular interest.

The Moon-based platform has different observation angular characteristics from artificial satellites due to its peculiar orbit. To illustrate the difference, we first normalize the positions and attitudes of the Sun, Earth, and Moon into the same ref
