Indian Space Research Organisation (ISRO)’s Aditya-L1’s payloads capture a series of solar flares from AR13664, providing valuable data on solar activity.

Active region AR13664 on the Sun erupted several X-class and M-class flares during May 8-15, 2024, causing a major geomagnetic storm on May 11, 2024.

Two remote sensing payloads on Aditya-L1 captured these events during May 8-9, 2024, while two in-situ payloads captured this event during May 10-11, 2024.

Payload Captures

The Solar Ultra Violet Imaging Telescope (SUIT) on Aditya-L1 captured Sun images on May 17, 2024, showing bright, active regions on the Solar disk.
