A Large Area Soft X-Ray Spectrometer (CLSS) payload on the Chandrayaan-2 Orbiter has detected solar proton events that are responsible for increased radiation exposure to humans in space.

Reported first by PTI, ISRO revealed that the instrument on January 18 also recorded CMEs (Coronal Mass Ejections) -- ionised charge particles released due to solar activity/ solar flares on the star¡¯s surface.?
CME travels at a speed of about 1000 km/s and it takes around two to three days to reach the Earth. They often have the ability to cause ionisation on large scales in the Earth¡¯s middle atmosphere and are responsible for lighting up the polar sky with breathtaking auroras.?
ISRO¡¯s official statement revealed that there were two M-class solar flares; one flare (M5.5) released energetic particles into interplanetary space whereas the other (M1.5) was accompanied by a Coronal Mass Ejection.
To the unaware, solar flares are classified in A, B, C, M and X class based on their strength and each letter adds a ten-fold increase to the energy output, indicating the M class flare would have been the second most impactful one, right after the X-class.?

The Solar Proton Event (SPEs) was also witnessed by NASA¡¯s Geostationary Operational Environmental Satellite (GOES) orbiting the planet but it managed to miss the CME event that Chandrayaan-2 orbiter caught.?
Chandrayaan-2 orbiter was part of the Chandrayaan 2 mission by ISRO where it was supposed to land the Vikram Lander on the South Pole of the Moon. Sadly the landing didn¡¯t go as planned resulting in a hard landing on September 7, 2019.?
However, ISRO revealed that the mission had achieved 98 percent success as the orbiter continues to share crucial data with the ground station.
