🌞 Aditya-L1 Mission: India’s first scientific mission dedicated to studying the sun, utilizing the VELC instrument developed by the Indian Institute of Astrophysics (IIA). VELC Instrument: The Visible Emission Line Coronagraph (VELC) allows for closer observation of the solar corona and provides data at shorter intervals than existing coronagraphs.
🌌 CME Observation: A coronal mass ejection (CME) was observed on July 5, 2024, with no associated solar flare, highlighting the instrument’s capabilities.
âš¡ Magnetic Instabilities: The data collected helps differentiate between magnetic instabilities that cause flares and CMEs, contributing to a better understanding of CMEs, contributing to a better
What causes coronal mass ejections? CMEs occur due to the complex interactions of magnetic fields on the Sun’s surface.
Â
How often do CMEs occur?
CMEs can happen several times a day, especially during solar maximum periods. What are the potential dangers of strong CMEs? Strong CMEs can disrupt satellite communications, power systems, and even endanger astronauts in space. How can we prepare for geomagnetic storms? Monitoring solar activity and having contingency plans for power outages can mitigate risks. Can CMEs affect climate change? While CMEs can influence short-term weather patterns, their long-term impact on climate change is still debated.\
What technologies are most vulnerable to CMEs? Satellites, GPS systems, and power grids are particularly susceptible to geomagnetic storms. Are there any benefits to CMEs?
They can create beautiful auroras and provide valuable data for scientific research.
