Aditya-L1 & Chandrayaan-2 Analyse Solar Storm Impact

  • 15 May 2024

On 14th May 2024, ISRO announced Aditya-L1 & Chandrayaan-2's detection and analysis of recent powerful solar storm, originating from sunspot region AR13664.

Key Points

  • Aditya-L1 Findings: Aditya-L1's SWIS instrument observes enhancement of solar wind alpha particle and proton flux, providing crucial insights into solar eruptive events.
  • Chandrayaan-2 Observations: Chandrayaan-2's XSM detects X-rays emitted by the sun and its corona, contributing to the understanding of solar activity from lunar polar orbit.
  • Solar Flare Impact: Multiple X-class solar flares and Coronal Mass Ejections (CMEs) affect Earth, causing disruptions to communication and GPS systems, particularly over high latitudes.
  • Minimal Disruptions in India: India experiences lower latitude advantages, avoiding widespread outages despite the solar storm's severity.
  • Satellite Operations: ISRO confirms normal operations of geostationary orbit spacecraft, with no disruptions reported for Earth Observation satellites.
  • Ground Observations: Observations from Thumba record significant increase in Total Electron Content values, indicating the storm's impact on Earth's ionosphere.
