Images of the Sun captured by Aditya-L1 during Solar Storm
Context:
The Indian Space Research Organisation released a series of images showcasing the Sun’s dynamic activities in May.
More on News
- The images were captured using the Solar UltraViolet Imaging Telescope (SUIT) and the Visible Emission Line Coronagraph (VELC) on the Aditya-L1 spacecraft.
- ISRO scientists have successfully protected over 50 Indian satellites from solar flare damage using data from May, costing Rs 50,000 crore.
Key Highlights
- 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.
- Instrument Details:
-
- 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.
Significance:
- 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.
Aditya-L1 Mission
- 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.
