The Aditya-L1 payload captured several X- and M-class flares associated with coronal mass ejections.

India’s first solar mission Aditya-L1 captured some images of the Sun, which ISRO released on Monday. These images are from the solar storm that occurred in May 2024. They were taken via two onboard remote sensing instruments mounted on the Aditya-L1 spacecraft.

It was the same solar storm, due to which the sky had turned red with a unique light in many parts of the world, including Ladakh in India.

These images are of coronal mass ejection.
Releasing the photos, ISRO wrote in a post on L1 captured several X- and M-class flares associated with coronal mass ejections.

From May 8 to 15, the active region AR13664 of the Sun caused several X-class and M-class flares. These were associated with the coronal mass ejection (CME) that occurred during May 8 and 9. These caused a large geomagnetic storm on May 11.

These photographs show the brightness of sunspots, the umbra, the penumbra and the beach. ISRO says this will help astrophysicists (scientists who research space phenomena) in studying solar flares, their energy distribution, sunspots, ultraviolet radiation at broad wavelengths and long-term solar variations.

What is coronal mass ejection (CME)?
CME and solar flare are two different things. It was previously believed that along with solar flares, CMEs also occur in the solar corona, but now scientists believe that it is not necessary for each CME to be accompanied by a solar flare. The name CME means that it comes out of the coronal layer of the sun. In reality, these are large gas bubbles in which magnetic field lines are wrapped.

When a CME is released from the Sun, millions of tons of charged particles from the Sun are also released into space. These particles move at a speed of 3 million kilometers per hour. If the direction of these particles is towards the Earth, then a geomagnetic storm can occur on the Earth. This geomagnetic storm is called in other words solar storm. This storm represents a disturbance of the Earth’s own magnetic field.

Due to the millions of tons of charged particles of CME, a very powerful magnetic field is created in CME and when this magnetic field collides with the Earth’s magnetic field, a terrible electromagnetic interference is created, the solar storm is the effect of this interference. . The first symptom of a solar storm is the aurora.

It means light in the sky that is bright enough to read a newspaper at night. Apart from this, solar storms can have many negative effects on Earth.

How does a solar storm form on the surface of the Sun?
The part of the Sun that we see from Earth is called the photosphere. This is not a solid surface, it just looks like a shiny round shape to us. Above is the atmosphere of the sun. The lowest layer of this atmosphere is called the chromosphere, while the upper layer is called the corona. It is normally not visible due to sunlight, but can be seen during a solar eclipse or using special instruments. Some events take place in this corona that give rise to solar storms.

The solar storm hit the earth on May 10

The world’s most powerful solar storm hit Earth after 20 years on Friday, May 10. Due to the storm, there was strong lightning in the sky from Tasmania to Great Britain. Many satellites and power grids were also damaged. Due to the solar storm, auroras were also observed in many places around the world. During this time, due to the solar storm, the sky appeared different colors. Read the full news…

Aditya-L1 reached the Lagrange point in 127 days
Aditya-L1 was launched on September 2, 2023. 127 days later, on January 6, 2024, it reached the Lagrangian point. L1 is about 1.5 million kilometers from Earth. The Aditya spacecraft can continuously capture the movements of the Sun from here without any interruption.
