The Extreme UV Imager (EUI) on-board Solar Orbiter consists of three telescopes, two high-resolution imagers providing information on the corona and the chromosphere, and an EUV full-disk imager that does not only allow to observe the whole solar disk but provides us with unprecedented information of the corona far above the limb in a coronagraphic mode. Hence, the scientific results through...
Aditya-L1, is an observatory class mission to study the solar dynamics and its influence in the inner heliosphere especially at the first Sun-Earth Lagrangian (L1) point. Aditya-L1 conceived with four remote sensing and three in-situ payloads. The remote sensing payloads carry out observations of the source regions of the dynamical events while the in-situ payloads observe the events at L1....
The European Solar Telescope (EST) will be equipped with a comprehensive suite of state-of-the-art intruments designed to observe the solar atmosphere at high spatial and temporal resolution and high polarimetric sensitivity. Among them are three Tunable-Imaging Spectropolarimeters/Fixed-Band Imagers (TIS/FBIs) that will provide diffraction-limited measurements of photospheric and...
National Large Solar Telescope, a state-of-the-art 2-meter telescope, is designed to revolutionize solar atmospheric research. Its primary goal is to conduct high-resolution observations, both spatially and spectrally, of the Sun's outer layers. To ensure optimal performance, a rigorous site characterization program was initiated in 2007. This led to the selection of two prime locations in the...
Since its installation in 2012, the Gregor Infrared Spectrograph (GRIS) has been operating with a single detector that could be tuned to any wavelength in the bands 1.0-1.3 microns or 1.5-1.8 microns in spectroscopic or spectropolarimetric mode, or in the band 2.0-2.3 microns in spectroscopic mode. Few years ago, a removable integral field unit (IFU) was added to the system to make the...
Solar coronal EUV/X-ray bright points (CBPs) are believed to be major contributors to quiet solar coronal heating. Solar Orbiter's EUI/\hri\ observations of an emerging flux region (a typical CBP) in 174 \AA, emitted by the coronal plasma at $\sim$1 MK, reveals the presence of numerous tiny bright dots. These dots are roundish with a diameter of 675$\pm$300 km, a lifetime of 50$\pm$35 seconds,...
The Gauribidanur Radio Observatory (GRO) is one of a few solar radio observatories functioning for the past few decades. It has four major facilities, viz., the Gauribidanur RAdioheliograPH (GRAPH), the Gauribidanur LOw-frequency Solar Spectrograph (GLOSS), the Gauribidanur Radio Interferometric Polarimeter (GRIP), and the Gauribidanur RAdio Spectro-polarimeter (GRASP). The GRAPH...
Suprathermal particles (with energies in the range from 10s of keV to 1-2 MeV) are thought to be the seed populations for solar energetic particles accelerated by shocks associated with interplanetary coronal mass ejections (ICMEs). Origins, energizations, and modulations of suprathermal particles in the interplanetary (IP) medium have been widely debated in the contemporary space era, thanks...
Parker Solar Probe has been trailblazing around the Sun for nearly half a solar cycle, delivering groundbreaking insights into its immediate atmosphere. To date, Parker has completed 21 of its scheduled 24 orbits during the prime science phase of the mission. The diverse and unparalleled quality data it gathers has captivated both the international space science community and the public. With...
