☀️ Aditya-L1 & Solar Storm Impacts – Short Notes

1️⃣ About Aditya-L1
India’s first solar mission
Launched by ISRO
Studies:
Solar wind
Solar storms
Sun–Earth interactions

2️⃣ Geomagnetic Storms – Meaning
Large disturbances in Earth’s magnetic field
Caused by changes in solar wind
Solar wind = continuous flow of charged particles from the Sun
📌 When:
Sudden increase/decrease in solar wind pressure hits Earth’s magnetosphere
➡ Sharp magnetic field changes occur

3️⃣ Key Observations (Solar Cycle 25)
Two intense geomagnetic storms:
10 May 2024
10 October 2024
Unusual dawn-time geomagnetic disturbances observed
Strange pattern in Earth's magnetic field response

4️⃣ Why Important?
Understanding magnetic field response helps because:
Solar wind variations can affect:
🛰 Satellites
📡 Navigation systems
⚡ Technological infrastructure

5️⃣ Major Insight
Combined data from:
Aditya-L1 spacecraft
Global ground magnetometer networks
Provided new understanding of:
How extreme solar wind alters normal geomagnetic disturbance patterns
