The Indian Space Research Organisation (ISRO) has released photographs depicting dynamic solar activities from May. These images were captured by the Aditya-L1 spacecraft.
The images were taken using the Solar UltraViolet Imaging Telescope (SUIT) and the Visible Emission Line Coronagraph (VELC) onboard Aditya-L1.
During the week of May 8-15, the active region AR13664, one of the largest sunspots recorded, erupted with several X-class and M-class flares, causing Coronal Mass Ejections (CMEs).
These solar events led to a major geomagnetic storm on May 11, captured by Aditya-L1's remote sensing payloads SoLEXS and HEL1OS, and in-situ payloads ASPEX and MAG.
SUIT images from May 17 show bright, active regions on the solar disk in the Mg II k line. These regions indicate magnetic activity, potentially leading to large solar flares.
The Narrow Band 276 nm images reveal sunspots and surrounding plages, with different bands highlighting variations at different atmospheric heights.
The VELC recorded coronal activities in the 5303 Angstrom emission line through raster scans on May 14, focusing on the active region AR 13664.
The VELC images used four slits to cover different corona regions, with a 20-minute raster duration. The images marked the solar photosphere edge and occulting disk extent, essential for observing faint coronal structures.
