Today’s full-disk solar image reveals the Sun’s chromosphere in remarkable detail, highlighting active regions AR 4478, AR 4479, and AR 4480 along with the intricate network of chromospheric fibrils surrounding them.
The image is a high-resolution mosaic composed of 30 individual panels, carefully captured and stitched together to preserve fine surface detail across the entire solar disk.
Hydrogen-alpha imaging allows us to observe a different layer of the Sun than ordinary white-light observations, revealing dynamic features shaped by the Sun’s powerful magnetic fields. Around the active regions, bright plages and dark sunspots mark areas of intense magnetic activity that continue to evolve from day to day.
