Context:

The Indian Space Research Organisation released a series of images showcasing the Sun’s dynamic activities in May.

Solar Storm Events: Between May 8 and 15, several X-class and M-class flares erupted in the active region AR13664 on the Sun. These eruptions were associated with Coronal Mass Ejections (CMEs).

Images Released: ISRO released six images of the Sun taken by the SUIT payload at different wavelengths.

- SUIT: Captured images at different wavelengths, revealing solar flares and sunspots.
- VELC: Carried out observations in the emission line 5303 Angstrom.
- SoLEXS and HEL1OS: Other remote sensing payloads on Aditya-L1 also captured solar events during this period.
- ASPEX and MAG: In-situ payloads captured the event on May 10 and 11 during Aditya-L1’s passage through the Sun-Earth L1 point.

Collaborative Observations: Observations were also made by the Chandrayaan-2 spacecraft, XPoSat, and ground-based facilities like the Udaipur Solar Observatory-Physical Research Laboratory.

These images help in studying solar flares, energy distribution, sunspots, space weather prediction, solar activity monitoring, and UV radiation over a wide wavelength range.
Understanding solar flares and their impact on Earth’s geomagnetic environment is important for space exploration and satellite communications.

India’s first solar mission.
Launched on September 2, 2023, via PSLV-C57 from the Satish Dhawan Space Centre at Sriharikota.
Objective: It intends to investigate the Sun’s corona and atmosphere from the L1 (Lagrange point).
- The location is crucial for the continuous and uninterrupted observation of solar events.
It reached the Lagrangian Point (L1), located 1.5 million km from Earth, in January 2024.

Lagrange Points

Positions in space where the gravitational pull of two large masses balances with the centripetal force required for a small object to move with them.
These points allow spacecraft to reduce fuel consumption needed to remain in position.
There are five Lagrange points in a two-body system:

- Three unstable points: L1, L2, L3 (lie along the line connecting the two large masses).
- Two stable points: L4 and L5 (form the apex of two equilateral triangles with the large masses at their vertices).
