Deciphering solar magnetic activity: on grand minima in solar activity [PDF]
Frontiers in Astronomy and Space Sciences, 2015 The Sun provides the energy necessary to sustain our existence. While the Sun provides for us, it is also capable of taking away. The weather and climatic scales of solar evolution and the Sun-Earth connection are not well understood. There has been tremendous progress in the century since the discovery of solar magnetism - magnetism that ultimately ...

Solar Activity and Solar Oscillations [PDF]
Symposium - International Astronomical Union, 1997 Helioseismology provides us with the tools to probe solar activity. So that we can consider how the solar oscillations are influenced by that activity, we first consider the phenomena that we associate with the active Sun. The surface of the Sun is not quiet but shows evidence of convection on a wide range of scales from a few hundred kilometres ...

The passband integration properties of Birefringent filter
Scientific Reports, 2021 In this article, we discuss an observation phenomenon where the total amount of photons in the full passband of the Birefringent filter is a constant number that is considered by removing the spectrum of the light source irrespective of the instrument ...

Guided filtering for solar image/video processing
Solar-Terrestrial Physics, 2017 A new image enhancement algorithm employing guided filtering is proposed in this work for enhancement of solar images and videos, so that users can easily figure out important fine structures imbedded in the recorded images/movies for solar observation ...
