First results from PADRE/MeDDEA: X-rays from a flare and its CME

The MeDDEA hard X-ray spectrometer onboard NASAs PADRE CubeSat operates four flight-spare detectors from the Solar Orbiter/STIX instrument. This paper aims to evaluate the accuracy of the MeDDEA calibration and to demonstrate that MeDDEA data are ready for scientific exploitation. Using the first joint observations bet...

Fine-scale flare structures and their energetic implications from short-exposure extreme-ultraviolet imaging

To capture the brightest and most rapidly evolving phases of solar flares, the Major Flare Solar Orbiter Observing Plan (SOOP) employs a dedicated short-exposure mode for the High Resolution Imager ( of the Extreme Ultraviolet Imager (EUI), providing high-cadence, high spatial-resolution extreme-ultraviolet (EUV) imagi...

Count-based spectral component imaging (CCI) of solar flares in X-rays

X-ray emission in solar flares is produced by both multi-thermal plasma and accelerated electrons. Classical imaging approaches reconstruct X-ray intensity maps which contain contributions from multiple spectral components (e.g., hot, superhot, and non-thermal), and do not allow retrieving the morphology of the differe...

In-Flight Self-Calibration of the STIX Grid Transmission

The Spectrometer/Telescope for Imaging X-rays (STIX) on board Solar Orbiter provides imaging information on the X-ray sources in solar flares by modulating the emitted radiation with pairs of grids made of stacked tungsten layers. Optical measurements of the grids were taken on the ground and utilized to derive an init...
