Chandrayaan-2 and Aditya-L1 Orbiter Record Solar Flares Behind Aurora Phenomenon, Announces ISRO


The Indian Space Research Organization (ISRO) recently announced a significant achievement in space research. The Chandrayaan-2 orbiter, along with the Aditya-L1 solar observatory, have successfully recorded data pertaining to solar flares, which are a primary cause behind the mesmerizing aurora phenomenon observed on Earth. This breakthrough adds a crucial chapter to our understanding of solar activities and their impact on space weather.

Unveiling Solar Secrets

Solar flares are intense bursts of radiation emanating from the release of magnetic energy associated with sunspots. The flares recorded by Chandrayaan-2 and Aditya-L1 are of particular interest because they help explain the complex solar activities that influence the Earth’s magnetic field and atmosphere, leading to the auroras. These natural light displays, typically seen in high-latitude regions around the Arctic and Antarctic, are not just stunning visual phenomena but also key indicators of solar-terrestrial interactions.


The data captured by these two spacecraft offer unprecedented details about the intensity and timing of solar flares. By analyzing this data, scientists can better predict when and how these solar events might affect satellite communications, navigation systems, and even power grids on Earth.

Chandrayaan-2 and Aditya-L1:

Chandrayaan-2, primarily known for its mission to explore the Moon, includes instruments capable of observing solar phenomena from lunar orbit. This strategic position allows for a unique perspective on the Sun-Earth system, unobstructed by Earth’s atmosphere. Aditya-L1, ISRO’s dedicated solar mission, is positioned at the Lagrange point 1 (L1) of the Sun-Earth system, which offers a constant view of the sun and facilitates continuous monitoring of solar activities.

The synergy between Chandrayaan-2 and Aditya-L1 provides a comprehensive observational network that enhances our understanding of space weather dynamics. This collaboration marks a significant stride in ISRO’s capabilities in multi-mission interdisciplinary research.

Technical Challenges and Innovations

Operating sophisticated instruments in the harsh environment of space poses numerous challenges. The instruments aboard Chandrayaan-2 and Aditya-L1 must withstand extreme temperatures and radiation levels while maintaining precision in data collection. ISRO has implemented advanced technology and engineering solutions to ensure that these spacecraft can deliver high-quality data.

The sensors used for recording the solar flares are equipped with high-resolution imaging capabilities and are tuned to observe various wavelengths of light and radiation emitted during these events. These technological advancements allow for a detailed analysis of the solar flare mechanisms and their propagation through space.

Impact on Global Space Weather Research

The findings from Chandrayaan-2 and Aditya-L1 have significant implications for global space weather research. By sharing this data with international space agencies and research institutions, ISRO contributes to a global pool of knowledge that supports the development of more accurate predictive models for solar activity. This collaborative effort is crucial in preparing for and mitigating the effects of space weather on modern technological systems.

Looking Ahead

The successful recording of solar flares by Chandrayaan-2 and Aditya-L1 is just the beginning. ISRO plans to further enhance its research in heliophysics with upcoming missions that aim to explore different aspects of the Sun and its influence on the solar system. These missions will not only deepen our understanding of fundamental solar processes but will also refine our approaches to space weather forecasting.


The collaborative achievements of Chandrayaan-2 and Aditya-L1 underscore ISRO’s growing prowess in space research and its commitment to advancing our understanding of the universe. The data from these missions will help safeguard Earth’s technological infrastructure and enhance our preparedness for solar events, benefiting societies worldwide. This pioneering work paves the way for future explorations and discoveries in the vast realm of space.
