Aditya-L1's SUIT takes first-ever full-disk representations of Sun | See pics

Indian Space Research Organisation (ISRO) shared the ‘first-ever full-disk representations of the Sun’ taken by Solar Ultraviolet Imaging Telescope (SUIT) instrument on board the Aditya-L1 spacecraft.

“The SUIT payload captures full-disk images of the Sun in near ultraviolet wavelengths. The images include the first-ever full-disk representations of the Sun in wavelengths ranging from 200 to 400 nm. They provide pioneering insights into the intricate details of the Sun's photosphere and chromosphere.” ISRO wrote on X.

Among the notable features revealed are sunspots, plage, and quiet Sun regions, as marked in the Mg II h image, providing scientists with pioneering insights into the intricate details of the Sun's photosphere and chromosphere, ISRO informed.

On November 20, 2023, the SUIT payload was powered ON. Following a successful pre-commissioning phase, the telescope captured its first light science images on December 6, 2023. 

“These unprecedented images, taken using eleven different filters include the first-ever full-disk representations of the Sun in wavelengths ranging from 200 to 400 nm, excluding Ca II h. The full disk images of the Sun in the Ca II h wavelength has been studied from other observatories”, ISRO wrote in their official statement.

SUIT observations will help scientists study the dynamic coupling of the magnetized solar atmosphere and assist them in placing tight constraints on the effects of solar radiation on Earth's climate

After the successful soft landing of Chandrayaan-3 near the South pole of the moon, the ISRO launched the country's maiden solar mission -- Aditya-L1 from the Satish Dhawan Space Centre in Sriharikota on September 2.

ISRO had said Aditya-L1 will neither land on the sun nor approach the sun any closer.

This strategic location will enable Aditya-L1 to continuously observe the sun without being hindered by eclipses or occultation, allowing scientists to study solar activities and their impact on space weather in real-time.

Also, the spacecraft's data will help identify the sequence of processes that lead to solar eruptive events and contribute to a deeper understanding of space weather drivers.
