Aditya L1, the spacecraft positioned at the Sun-Earth L1 Lagrange point, captured dynamic activities on the Sun during a solar storm that impacted Earth on May 11, 2024. The active region AR13664, one of the biggest sunspots in history, erupted powerful X-class and M-class flares associated with coronal mass ejections (CMEs), triggering geomagnetic storms on Earth.

Comprehensive Observations from Aditya L1

The Indian Space Research Organisation (ISRO) utilized its Aditya L1 spacecraft to observe the solar storm. Remote sensing payloads like SoLEXS and HEL1OS recorded the flares, while in-situ payloads ASPEX and MAG observed the storm’s signatures as it passed through L1. Chandrayaan-2 also contributed valuable observations from its vantage point around the Moon.

Aditya-L1 Mission Details

SUIT and VELC instruments on Aditya L1 captured the Sun’s activities in May 2024. X-class and M-class flares, along with CMEs, were recorded, leading to significant geomagnetic storms. After calibration operations, SUIT and VELC resumed observations, providing insights into the solar corona and magnetically active areas on the Sun.

Ground-Based Contributions

The Udaipur Solar Observatory of the Physical Research Laboratory also contributed to ISRO’s observations. By combining data from multiple sources, ISRO gathered a comprehensive dataset on the solar storm, advancing our understanding of space weather phenomena.
