The Inouye Solar Telescope Delivers Record-Breaking Images of Solar Flare, Coronal Loops

Amazing stuff!

What little we still know about our star! What if the sun is responsible for most of climate change on earth and not the spurious life essential trace gas CO2?

"On August 8, 2024, the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope captured the sharpest-ever images of a solar flare at the H-alpha wavelength (656.28 nm), revealing dark coronal loop strands in unprecedented detail. The observations, made during the decay phase of an X1.3-class flare, measured loop widths averaging 48.2 km, with some even half as narrow.
By using the Inouye Solar Telescope to isolate light at the H-alpha wavelength, emitted by hydrogen atoms, solar physicists can identify fine structures in the lower solar atmosphere too small to observe in the past—offering a potential breakthrough in determining the fundamental scale of coronal loops and advancing solar flare modeling. By improving researchers’ ability to model solar flares, these observations will also improve forecasting for space weather events that are hazardous to satellites, power grids, and communications on Earth. ..."

"A high-resolution image of the flare from the Inouye Solar Telescope, taken on August 8, 2024, at 20:12 UT. The image is about 4 Earth-diameters on each side. Labels of the different relevant regions of the image are added for clarity: flare ribbons (bright areas of energy release in the dense lower solar atmosphere) and an arcade of coronal loops (arcs of plasma outlining magnetic field lines that transport energy from the corona to the flare ribbons)."
