ISRO's Aditya-L1 Spacecraft Captures Solar Activity

Context

ISRO's Aditya-L1 spacecraft, equipped with two remote sensing instruments - Solar Ultra Violet Imaging Telescope (SUIT) and Visible Emission Line Coronagraph (VELC), has captured recent solar activity.

Key-highlights:

Aditya-L1 reached the Lagrangian point (L1) in January 2024, 127 days after its launch on in September 2023. L1 is approximately 1.5 million km from Earth, allowing continuous observation of the Sun.
Remote Sensing Instruments: SUIT and VELC onboard Aditya-L1 have recorded dynamic activities of the Sun during May 2024.
SUIT captures solar ultraviolet images, while VELC observes visible emission lines from the Sun.
Solar Events Recorded: Several X-class and M-class flares, accompanied by Coronal Mass Ejections (CMEs), were detected during May 2024, leading to significant geomagnetic storms.
The active region AR13664 on the Sun erupted multiple X-class and M-class flares during May. These events caused major geomagnetic disturbances.

Fact Box:

About Aditya-L1

Aditya-L1 is a satellite dedicated to the comprehensive study of the Sun.
The orbiter carries seven scientific instruments to observe and study-
- the solar corona (the outermost layer)
- the photosphere (the Sun's surface or the part we see from the Earth)
- the chromosphere (a thin layer of plasma that lies between the photosphere and the corona)
Aditya L1 is India's first space-based mission to study the solar system's biggest object

Basic Concepts:

Coronal Mass Ejections (CMEs): Powerful eruptions of solar plasma and magnetic field from the Sun's corona into space.
Solar Flares: Sudden bursts of energy and radiation from the Sun's surface, often associated with magnetic disturbances and emissions across the electromagnetic spectrum.
Geomagnetic Storms: Disturbances in Earth's magnetic field caused by interactions with solar wind and CMEs, potentially leading to disruptions in communication systems and power grids.
Lagrangian point (L1): L1 is a location in space where the gravitational forces of two celestial bodies, such as the Sun and Earth, are in equilibrium. This allows an object placed there to remain relatively stable with respect to both celestial bodies. L1 is located 1.5 million km (932,000 miles) from the Earth, which is 1% of the Earth-Sun distance.
