Aditya-L1 decoded how solar storms impact earth’s magnetic field: ISRO, Pg10

Key Highlights:

• ISRO's Aditya-L1 provided insights on how solar storms impact Earth's magnetic field.
• A study published in December in The Astrophysical Journal analyzed a major space weather event in October 2024.
• The study used data from Aditya-L1 and other international missions.
• A turbulent region of a solar storm compressed Earth’s magnetic field, affecting satellites.

Detailed Insights:

• Space weather events, like solar plasma eruptions, can disrupt satellites, communication, navigation, and power grids.
• The solar storm compressed Earth's magnetic field, pushing it closer and exposing satellites in geostationary orbit to harsh conditions.
• During the turbulent phase, currents intensified in the auroral region, potentially heating the upper atmosphere and increasing atmospheric escape.
• The Aditya-L1 mission helps in understanding and mitigating the effects of solar events on terrestrial and space-based infrastructure.

Key Concepts Involved:

• Solar Storm: A disturbance on the Sun that can emit energy in various forms.
• Geostationary Orbit: An orbit where a satellite appears stationary relative to a point on Earth.
• Auroral Region: High-latitude regions around the Earth's poles where auroras occur.
